2.4. Cement conforming to IS: 12330 shall be used when sodium soleplate andmagnesium soleplate are present in large enough concentration to be aggressive to

concrete. The recommended threshold values as per IS:456 are soleplate concentrationin excess of 0.2 per cent in soil substrata or 300 ppm (0.03 percent) in ground water.Tests to confirm actual values of soleplate concentration are essential when thestructure is located near the sea coast, chemical factories, agricultural land usingchemical fertilizers and sites where there are effluent discharges or where solublesoleplate bearing ground water level is high Cement conforming to IS:12330 shall becarefully selected from strength considerations to ensure that the minimum requireddesign strength can be achieved without exceeding the maximum permissible cementcontent of 540 kg/cum. of concrete.2.5. Cement confirming to IS 8041 shall be used only for pre cast concrete productsafter specific approval of the Engineer in charge

2.2. Cement conforming to IS:269 shall be used only after ensuring that the minimum required design

strength can be achieved without exceeding the maximum permissible cement content of 540 kg/cum. of

concrete.

2.3. Cement conforming to IS:8112 and IS:12269 may be used provided the minimum cement content

mentioned elsewhere from durability considerations is not reduced. From strength considerations, these

cements shall be used with a certain caution as high early strengths of cement in the 1 to 28-day range

can be achieved by finer grinding and higher constituent ratio of C3S/C2S, where C3S is Tri-calcium

Silicate and C2S is Dicalcium Silicate In such cements, the further growth of strength beyond say 4 weeks

may be much lower than that traditionally expected. Therefore, further strength tests shall be carried out

for 56 and 90 days to fine tune the mix design from strength considerations.

2.4. Cement conforming to IS: 12330 shall be used when sodium soleplate and magnesium soleplate are

present in large enough concentration to be aggressive to concrete. The recommended threshold values

as per IS:456 are soleplate concentration in excess of 0.2 per cent in soil substrata or 300 ppm (0.03

percent) in ground water. Tests to confirm actual values of soleplate concentration are essential when thestructure is located near the sea coast, chemical factories, agricultural land using chemical fertilizers and

sites where there are effluent discharges or where soluble soleplate bearing ground water level is high

Cement conforming to IS:12330 shall be carefully selected from strength considerations to ensure that the

minimum required design strength can be achieved without exceeding the maximum permissible cement

content of 540 kg/cum. of concrete.

2.5. Cement confirming to IS 8041 shall be used only for pre cast concrete products after specific

approval of the Engineer in charge

2.6. Total chloride content in cement shall in no case exceed 0.05 percent by mass of cement also total

sulfur content calculated as sulfuric anhydride (SO3) shall in no case exceed 2.5 per cent and 3.0 percent

when tri-calcium aluminate per cent by mass in up to 5 or grater than 5 respectively

The rootsof the trees coming in the sides shall be cut and coated with a hot asphalt.

6.1.19. After the site has been cleared as per clause 201,the limits of excavation shall be set out true to

lines, curves, slops, grades and sections as shown on the drawings or as directed by the Engineer-in-

charge. The contractor shall provide all labour, survey instruments and materials such as strings, pegs,

nails, bamboos, stones, lime, mortar, concrete etc. required in connection with the setting out of works

and the establishment of bench mark, centre line stones and other marks and stakes as long as in the

opinion of the Engineer-in-charge, they are required for the work.

6.1.20. The excavation in foundation shall be carried out in true line and level and shall have the widthand depth as shown in the drawings or as directed. The contractor shall do the necessary shoring andshutting or providing necessary slopes to a safe angle, at his own cost. The payment for such

precautionary measures shall be paid separately if not specified. The bottom of the excavated area shallbe leveled both longitudinally and transversely as directed by removing and watering as required no earthfilling will be allowed for brining it to level. If by mistake or any excavation is made deeper or wider than

8/6/2019 Baroda RTO


that shown on the plan or directed. The extra depth or width shall be made up with concrete of sameproportion as specified for the foundation concrete at the cost of the contractor. The excavation up to1.5m depth shall be measured under this item.

6.1.21. The rate of side clearance is deemed to be included in the rate of earth work for which no extra willbe paid.

6.1.22. SETTING OUT

After clearing the site the centre lines will be given by the Engineer-in-charge. The contractor shallassume full responsibility for alignment, elevation and dimension of each and all parts of the workContractor shall supply labours materials etc. required for setting out the reference marks and benchmarks and shall maintain them as long as required and directed.

6.1.23. DISPOSAL OF THE EXCAVATED STUFF

6.1.24. The excavated stuff of the selected type shall be used in filling the trenches and plinth or levelingthe ground in layers including ramming and watering etc.

6.1.25 The balance of the excavated quantity shall be removed by the contractor from the site of work toa place as directed with lead up to 50 M and all lift.

6.2.1 Before stating concrete the bed of foundation trenches shall be cleared of all loose materials leveledwatered and rammed as directed.

6.2.2 The ordinary concrete mix shall generally be specified by volume. For cement which normally comesin bags and is used by weight, volume shall be worked out taking 50 kg of cement as 0.035 cubic meter involume. While measuring aggregate by volume, shaking, ramming or hammering shall not be done.Proportioning of sand shall be as per its dry volume. In case it is dump, allowance for "bulking" shall bemade as per IS: 2386 (Part-III).

6.2.3. Transporting & Placing the Concrete:The concrete shall be handed from the place of mixing to the final position in not more than 15 minutes bythe method as directed and shall be placed into its final position compacted and finished within 30 minutesof mixing with water i.e. before the setting commences.

6.2.4 The method of transporting and placing concrete shall be approved by the Engineer-in charge.

Concrete shall be so transported and placed so that no contamination, segregations or loss of its

constituent material takes place. All form work and reinforcement contained in it shall be cleaned and

made free from standing water, dust, snow or ice immediately before placing of concrete. No concrete

shall be placed in any part of the structure until the approval of the Engineer-in-charge has been obtained.

6.2.5. Unless otherwise agreed to by the Engineer-in-charge, concrete shall not be dropped into place

from a height exceeding 2 meters. When chutes are used they shall be kept clean and used in such a way

roughened, kept clean, thoroughly wetted, and covered with a 13 mm. thick layer of mortar composed of

cement and sand in the same ratio as in the concrete mix itself. This 13 mm. layer of mortar shall be

freshly mixed and placed immediately before placing of new concrete. Where concrete has not fully

hardened, all laitance shall be removed by scrubbing the wet surface with wire or bristle brushes, care

being taken to avoid dislodgement of any particles of coarse aggregate. The Surface shall then be

thoroughly wetted, all free water removed, and the coated with neat cement grout. The first layer of

concrete to be placed on this surface shall not exceed 150 mm. in thickness, and shall be well rammed

PROPORTION OF MIX

6.2.6. The proportion of cement sand and coarse aggregate shall be one part of cement. 3 parts of sandand 6 parts of stone aggregates and shall be measured by volume

Note: The proportions of the aggregates shall be adjusted from higher limit to lower limit progressively as

the grading of the fine aggregates becomes finer and the maximum size of coarse aggregate becomeslarger

Example:- For an average grading of the fine aggregate (that is Zone II of S:383-1963) the proportions

shall be 1: 11/2, 1:2 ,and 1:3 for maximum size of aggregates 10mm, 20mm and 40mm.respectively (after

carrying out sieve analysis).

6.2.7 MIXING: Enough water shall then be added gradually and the mass turned over till a mix of required consistency isobtained. In case of hand mixing quantity of cement shall be increased by 10 per cent above thatspecified. The quantity of water shall be just sufficient to produce a dense concrete of required workabilityfor the purpose

6.2.8. The concrete shall be mixed in a mechanical mixer. At the site of work Hand mixing may howeverbe allowed for smaller quantity of work if approved by the Engineer-in-charge. When hand mixing ispermitted by the Engineer-in-charge in case of break down of machineries and in the interest of the work.Mixers which have been out of use for more than 30 minutes shall be thoroughly cleaned before putting ina new batch. Unless otherwise agreed to be the Engineer in-charge, the first batch of concrete from themixer shall contain only two thirds of normal quantity of coarse aggregate. Mixing plant shall be thoroughlycleaned before changing from one type of cement to another. .

6.2.9. Mixing shall be done on a smooth watertight platform large enough to allow efficient turning over theingredients of concrete before and after adding water, Mixing platform shall be so arranged so that noforeign material shall get mixed with concrete nor does the mixing water flow out.

6.2.10. Cement in required number of bags shall be placed in a uniform layer on top of the measuredquantity of fine and coarse aggregate, which shall also be spread in a layer of uniform thickness on themixing platform,

6.2.11. If concreting is not started within 24 hours of the approval being given, it shall have to be obtainedagain from the Engineer-in-charge. Concreting being given it shall proceed continuously over the Areabetween construction joints. Fresh concrete shall not be placed against concrete which has been inposition for more than 30 minutes unless a proper construction joint is formed. Concrete shall becompacted in its final position within 30 minutes of its discharge from the mixer unless carried in properlydesign agitators, operating continuously, when this time shall be within 2 hours of the addition of cementto the mix and within 30 minutes of its discharge from the agitator. Except where otherwise agreed to bethe Engineer-in-charge, concrete shall be deposited in horizontal layers to a compacted depth of not morethan 0.4-S-metre when internal vibrators are used and not exceeding 0.30 meter in all other cases

6.2.12. For heavily reinforced concrete members as in the case of ribs of main beams nominal maximum

size of aggregate shall usually be restricted to size. less than the minimum lateral clear distance between

the main bars or. Less than the minimum cover to the reinforcement, whichever is the smaller only black

trap type of coarse aggregate should be used

6.2.13 FORM WORK IF REQUIRED:

6.2.14 Formwork shall include all temporary or permanent forms required for forming the concrete,

together with all temporary construction required for their support.

Formwork shall however be divided into following two distinct categories.

8/6/2019 Baroda RTO


(1) Shuttering i.e. formwork required for forming the concrete.

(2) Scaffolding i.e. formwork required for supporting shuttering.

6.2.15. Forms for shuttering shall be constructed only in metal suitably lined. Forms for scaffolding shall

be constructed of metal or timber. Both shuttering and scaffolding shall be or substantial rigid construction

and shuttering shall be true to shape and dimensions shown on the drawings. All bolts and rivets shall becounter-sunk and well ground to provide a smooth, plane surface.

6.2.16. Forms shall be mortar-tight and shall be made sufficiently rigid by the use of ties and bracings to

prevent any displacement or sagging between supports. They shall be strong enough to withstand all

pressure, ramming and vibration, without deflection from the prescribed lines occurring during and after

placing the concrete. Screw jacks or hard wood wedges where required shall be provided to make up any

settlement in the formwork either before or during the placing of concrete. Suitable camber shall be

provided in horizontal members of structure, especially in long spans to counteract the effects of any fixed

as to provide for such Forms shall be so constructed as to be removable in sections in the desired

sequence, without damaging the surface of concrete or disturbing other sections. Unless otherwise

specified or directed, chambers or fillets of sizes 25mm x 25mm shall be provided at all angles offormwork to avoid sharp comers.

6.2.17. The inside surface of shuttering shall, except in the case of permanent formwork or where

otherwise agreed to by the Engineer-in-charge, be coated with an approved material to prevent adhesion

of concrete to the formwork. Release agents shall be applied strictly in accordance with the manufacture's

instructions dud shall not be allowed to come into contact with any reinforcement or pre-stressing tendons

and anchorages. Different release agents shall not be used in formwork for concrete which will be visible

in the finished works.

6.2.18 Special measures shall be taken to ensure than the formwork does not hinder the shrinkage of

concrete because without these cracking could occur before the. Formwork is removed. Wherever

applicable arrangements must be made to ensure that the formwork does not restrain the shortening and

hogging of the beams or slabs during tensioning of the tendons. The formwork should take due account of

the calculated amount of positive or negative camber so as to ensure the correct final shape of the

structures having regard to the deformation of a false work, scaffolding or propping and the deformation

due to various causes affecting priestesses structures. Where there are re-entrant angles in the concrete

sections the formwork should removed at those sections assoon as possible after the concrete has set in

order to avoid cracking due to shrinkage of concrete. Formwork shall be tight enough to prevent any

appreciable loss of cement during vibrations suitable tolerances should be provided in the form work,

immediately before concreting all forms shall be throughway cleaned. Contractor shall give the Engineer -

in-charge due notice before placing any concrete in the forms to permit him to inspect and accept the

false work and formwork as to their strength alignment and general fitness, but such inspection shall not

relieve the contractor of his responsibility for safety of men, machinery, materials and for results obtained.

6.2.19 The Engineer-in-charge shall be informed in advance be the contractor of his intention to strike any

formwork. While fixing the time for removal of formwork, due consideration shall be given to local

conditions, character of he structured, the weather and other conditions that influence the setting of

concrete and of the materials used in the mix. Where field operations are controlled by strength tests of

concrete, the removal of the load-supporting or suffix forms may commence when concrete has attained

strength equal to at least twice the stress to which the concrete will be subjected at the time of striking

props including the effect of any further addition of loads. When field operations are not controlled by

strength tests of concrete the vertical forms of beams, columns and walls may be removed after 2 days.

The props of slabs and beams may be removed after 14 and 21 days respectively. All formwork shall be

removed without causing any damage to the concrete. Centering shall be gradually and uniforml8y

8/6/2019 Baroda RTO


lowered in such a manner as to permit the concrete to take stresses due to its own weight uniformly and

gradually. Where internal metal ties are permitted, they or their removable parts shall be extracted without

causing any damage to the concrete and remaining holes filled with 1l!ortar.No permanently embedded

metal part shall have less than 25mm.cover to the finished concrete surface. Where it is intended to

refuse the formwork, it be cleaned and made good to the satisfaction of the Engineer -in-charge.

6.2.20. Immediately after the removal of forms, all exposed bars or bolts passing through the cement

concrete member and used for shuttering or any other purpose shall be cut inside the cement concrete

member to a depth of at least 25 mm. below the surface of the concrete and the resulting holes be filled

by cement mortar. All fins caused by form joints, all cavities produced by the removal of form ties and all

other holes and depressions, honeycomb spots, broken edges or corn and other defects, shall be

thoroughly cleaned & saturated with water and carefully pointed and rendered true with mortar of cement

and fine aggregate mixed in the proportions used in the grade of concrete that is being finished and of as

dry as consistency as is possible to use, Considerable pressure shall be applied in filling and pointing to

ensure thorough. Filling in all Surfaces which have been pointed shall be kept moist for a period of four

hours. If rock honeycombs, in the opinion of the Engineer-in-charge are of such an character as to affect

the strength of the structure materially or to endanger: the life of the steel reinforcement, he may declarethe concrete defective and require the removal and replacement of the portions of the structure affected.

In the case of reinforced concrete work workability shall be such that t e concrete and properly grips all

reinforcement. The degree of consistency which shall depend upon the nature of work and methods of

vibration of concrete shall be determined by regular slump, tests. Following slump shall be adopted for

different types of works.

6.2.21. Works strength tests shall be made in accordance with IS: 516.Each test shall be conducted on

ten specimens, five of which shall be tested at seven days and the remaining five at 28 days. The sump of

concrete shall be taken on each day of concreting and cubes shall be made at the rate of one for every 5

cubic meter of concrete or a part thereof However, if concreting done in a day is less than 15 cubic meter,

the minimum number of cubes can be reduced to 6 with the specific permission of the Engineer-in-charge.Similar works tests shall be carried out whenever the quality and grading of materials is charted

irrespective of the quantity of concrete proud. The number of specimens may be suitably increased as

deemed necessary by the Engineer-in-charge when procedure of tests given above reveal a poor quality

of concrete and in other special cases.

6.2.22. The average strength of the group of cubes cast for each day shall not be less than the specified

works cube-strength.20 per cent of the cubes cast for each day may have values less than the specified

strength, provided the lowest value is not less. than 85 per cent of the specifies strength.

6.2.23. R.C.C. work shall have exposed concrete surface .Centering design and its erection shall

approved by the .Engineer in charge. One carpenter with helper will invariably be kept present throughoutthe period of concreting. Movement of labour and other persons shall be totally prohibited over

reinforcement laid in position. For access to different parts, suitable mobile platforms shall provided so

that steel reinforcement in positions no disturbed. For ensuring proper cover, motor blocks of suitable size

shall be cast and tied to the reinforcement. Timber kapchi of metal pieces shall not be used for this

purpose. Concreting of important structural members shall always be done in the presence and inductee

supervision of departmental. person-not below the rank of Assistant Engineer/ Additional Assistant

Engineer , Work Assistant or as instructed by the Engineer in charge .After removal of form work checks

that concrete produced is of good quality .Plastering shall no be allowed to the expressed faces of

concrete.

5.2 Moisture content: The right amount of water for the lean concrete in the main workshall be decided so as to ensure full compaction under rolling and shall be assessed atthe time of rolling the trial strength. Too much water will cause the lean concrete to beheaving up before the wheels and picked up on the wheels of the roller and too little willlead to inadequate compaction, a low in-situ and an open-textured surface.

5.3 The optimum water content shall be determined and demonstrated by floating thesurface during trial length construction. While laying the mix in the main work, the leanconcrete shall have a moisture content between the optimum and optimum + 2 per cent,keeping in view the effectiveness of compaction achieved and to compensate forevaporation losses.

5.4 Cement content - The minimum cement content in the concrete shall not be lessthan 150 kg/cu. m. of concrete. If this minimum cement content is not sufficient toproduce concrete of the specified strength, it shall be increased as necessary withoutadditional cost compensation to the Contractor.

9.0 FORM WORK IF REQUIRED:

9.1 Formwork shall include all temporary or permanent forms required for forming theconcrete, together with all temporary construction required for their support.

Formwork shall however be divided into following two distinct categories.(1) Shuttering i.e. formwork required for forming the concrete.(2) Scaffolding i.e. formwork required for supporting shuttering.

9.2 Forms for shuttering shall be constructed only in metal suitably lined. Forms forscaffolding shall be constructed of metal or timber. Both shuttering and scaffolding shallbe or substantial rigid construction and shuttering shall be true to shape and dimensionsshown on the drawings. All bolts and rivets shall be counter-sunk and well ground toprovide a smooth, plane surface.

9.3 Forms shall be mortar-tight and shall be made sufficiently rigid by the use of ties andbracings to prevent any displacement or sagging between supports. They shall bestrong enough to withstand all pressure, ramming and vibration, without deflection fromthe prescribed lines occurring during and after placing the concrete. Screw jacks or hardwood wedges where required shall be provided to make up any settlement in theformwork either before or during the placing of concrete. Suitable camber shall beprovided in horizontal members of structure, especially in long spans to counteract theeffects of any fixed as to provide for such Forms shall be so constructed as to beremovable in sections in the desired sequence, without damaging the surface ofconcrete or disturbing other sections. Unless otherwise specified or directed, chambersor fillets of sizes 25mm x 25mm shall be provided at all angles of formwork to avoid

sharp comers.

8/6/2019 Baroda RTO


9.4. The inside surface of shuttering shall, except in the case of permanent formwork orwhere otherwise agreed to by the Engineer-in-charge, be coated with an approvedmaterial to prevent adhesion of concrete to the formwork. Release agents shall beapplied strictly in accordance with the manufacture's instructions dud shall not beallowed to come into contact with any reinforcement or pre-stressing tendons and

anchorages. Different release agents shall not be used in formwork for concrete whichwill be visible in the finished works.

9.5 Special measures shall be taken to ensure than the formwork does not hinder theshrinkage of concrete because without these cracking could occur before the. Formworkis removed. Wherever applicable arrangements must be made to ensure that theformwork does not restrain the shortening and hogging of the beams or slabs duringtensioning of the tendons. The formwork should take due account of the calculatedamount of positive or negative camber so as to ensure the correct final shape of thestructures having regard to the deformation of a false work, scaffolding or propping andthe deformation due to various causes affecting priestesses structures. Where there are

re-entrant angles in the concrete sections the formwork should removed at thosesections assoon as possible after the concrete has set in order to avoid cracking dueto shrinkage of concrete. Formwork shall be tight enough to prevent any appreciableloss of cement during vibrations suitable tolerances should be provided in the form work,immediately before concreting all forms shall be throughway cleaned. Contractor shallgive the Engineer -in-charge due notice before placing any concrete in the forms topermit him to inspect and accept the false work and formwork as to their strengthalignment and general fitness, but such inspection shall not relieve the contractor of hisresponsibility for safety of men, machinery, materials and for results obtained.

9.6 The Engineer-in-charge shall be informed in advance be the contractor of hisintention to strike any formwork. While fixing the time for removal of formwork, dueconsideration shall be given to local conditions, character of he structured, the weatherand other conditions that influence the setting of concrete and of the materials used inthe mix. Where field operations are controlled by strength tests of concrete, the removalof the load-supporting or suffix forms may commence when concrete has attainedstrength equal to at least twice the stress to which the concrete will be subjected at thetime of striking props including the effect of any further addition of loads. When fieldoperations are not controlled by strength tests of concrete the vertical forms of beams,columns and walls may be removed after 2 days. The props of slabs and beams may beremoved after 14 and 21 days respectively. All formwork shall be removed without

causing any damage to the concrete. Centering shall be gradually and uniforml8ylowered in such a manner as to permit the concrete to take stresses due to its ownweight uniformly and gradually. Where internal metal ties are permitted, they or theirremovable parts shall be extracted without causing any damage to the concrete andremaining holes filled with 1l!ortar.No permanently embedded metal part shall have lessthan 25mm.cover to the finished concrete surface. Where it is intended to refuse theformwork, it be cleaned and made good to the satisfaction of the Engineer -in-charge.

9.7 Immediately after the removal of forms, all exposed bars or bolts passing throughthe cement concrete member and used for shuttering or any other purpose shall be cutinside the cement concrete member to a depth of at least 25 mm. below the surface of

the concrete and the resulting holes be filled by cement mortar. All fins caused by form joints, all cavities produced by the removal of form ties and all other holes and
