Concrete is a composite material composed

of aggregate bonded together with a

fluid cement which hardens over time. Most use of

the term "concrete" refers to Portland cement.

The manufacture and use of concrete produce a wide

range of environmental and social consequences.

A major component of concrete is cement, which

similarly exerts environmental and social effects.

Cement manufacture causes environmental impacts at all

stages of the process. These include emissions of

airborne pollution in the form of dust, gases, noise.

The amount of CO2 emitted by the cement industry is

nearly 900 kg of CO2 for every 1000 kg of cement

produced.

So, reducing CO₂ emission by partial replacement of

cement using advance construction material silica fume

as well as nano silica.

Conclusion

Review

1)Effect of used foundary sand & pozzocrete partial

replacement with F.A. & Cement in concrete by Dushyant

Bhimani , Jayesh kumar Pitroda & Jaydev Bhavsar Concludes

• Pozzocrete P60 and used foundry sand can be used to

prepared low cost temporary structure.

• The results indicate that the % change in cost reduce up to

5.17 for 50% replacement of used foundry sand plus 10%

replacement of pozzocrete

2)Use of used foundary sand in concrete :A state of review

by Smit M. Kacha , Abhay V. Nakum, Ankur C. Bhogayata

Conclude that,

• Concrete up to 30-40% replacement of fine aggregate

with foundry sand in which compressive and tensile

strength is increased up to 20% whereas not much change

occurs in modulus of elasticity.

• Workability is decreases with the increase of foundry

sand content because of very fine particles.

• Concrete made with foundry sand can be suitably used in

making structural grade concrete

3) Performance of Portland cement mixes containing silica

fume and mixed with lime-water by Metwally A.A. Abd

Elaty , Mariam Farouk Ghazy Concludes that,

The combined use of SF and LW in Portland cement

concrete mixes delayed both initial and final setting times.

The maximum delay in initial setting time was noticed

83% over the control mix.

33.2% increase of the compressive strength was

recorded for mix C30LW at 60 days age.

4) Charactarastics of blended cement containing silica by

Mohamed Heikal a, S. Abd El Aleem b, W.M. Morsi

The water demand and setting times of OPC–GBFS–

Silica increase with Silica content; this is due to the

retardation of the setting in the presence of 1% of super

plasticizer.

The compressive and flexural strengths of OPC–

GBFS–Silica cement mortars containing Silica are higher

than those of OPC–GBFS control mix (M3).

5) Influence of nano materials on flexural behavior and

compressive strength of concrete by Anawar Mohhamad.

Partially replacing cement with nano silica upto 3.75%

Improvement in flexural strength by 4 to 8% at interval

of 90 days.

6) Experimental study of the effect of addition of nano-

silica on the behavior of cement mortars by Mounir Ltifia,

Achraf Guefrech, Pierre Mounangab,d, Abdelhafid Khelidj

Compressive strengths increase with increasing the nano-

SiO2 content.

The influence of nano-SiO2 on consistency and setting

time are different. Nano-SiO2 makes cement paste thicker

and accelerates the cement hydration process

7) Investigation of Mechanical and Durability Properties of

Concrete Influenced by Hybrid Nano Silica and Micro

Zeolite by H. Eskandaria,, M. Vaghefib, K. Kowsaric

In this experiment replacing cement with max 2% nano

silica and 10% microzeolite.

The optimized mixture for achieving high quality of

durability is incorporation of 2% nano silica and 8% micro

zeolite.

Decrease rate of tensile strength is less than compressive

strength in all ages.

To check the Compatibility of Combination of Industrial

waste (Used Foundary sand) and Advance Construction

material (Silica fume) in the Concrete.

Also comparing earlier and later compressive strength

of concrete using silica fume and Nano silica .

OBJECTIVES OF STUDY

By using industrial waste we will make the environment

friendly concrete.

silica fumes & nanosilica .

To study the effect on strength by replacement of

aggregate by used Foundary sand and cement with

silica fume.

Comparing the compressive strength of concrete with

silica fume & nano silica

Utilization of Used Foundary sand, silica fume and

Nano silica in the Concrete by carryout various

destructive tests on concrete.

28 Days

150 mm × 150 mm × 150 mm concrete cubes are cast

by using M25 grade concrete. After 24 h the

specimens is remove from the mould and subjected to

water curing for 7, 14 and 28 days. After curing, the

specimens are tested for compressive strength using a

calibrated compression testing machine of 2,000 KN

capacities.

Compressive strength = P/A

Where, P = failure load(peak)

A= cross sectional area

150 mm Dia. & 300 mm Height concrete cylinders

are cast by using M25 grade concrete. After 24 h the

specimens is remove from the mould and subjected to

water curing for 28 days. After curing, the specimens

are tested for tensile strength using a calibrated

tensile testing machine of 2,000 KN capacities.

Tensile Strength = 2p/Π*l*d

p= maximum load in newton applied to specimen

I = length of the specimen

d = cross sectional dimension of the specimen

The 150mm×150mm×150mm block after casting will be

immersed in water for 28 days curing. These specimens

will then oven dried for 24 hours at the temperature 110°C

until the mass became constant and again weighed. This

weight was noted as the dry weight (W1) of the block.

After that the specimen will be kept in water for 24 hours.

Then this weight will noted as the wet weight (W2) of the

block.

% Water Absorption = [(W2 – W1) / W1] x 100

Where,

W1 = Oven dry weight of cylinder in grams

W2 = After 24 hours wet weight of cylinder in grams.

This test was carried out on the cube of

150mm*150mm*150mm. Cubes are casted and

demoulded after 24 hours and at the ends of 28 days of

normal curing period tested.

The specimens were taken out from the curing tank and

initial weight was taken. 5% of sodium sulphate (Na2SO4)

and 5% magnesium sulphate (MgSO4) by weight of water

was added with water as per earlier investigators and a set

of specimens were immersed continuously for a period of

28 days to determine the sulphate resistance of the

concrete with and without mineral admixtures.

% Change In Weight = (W2-W1/W1) X 100

Silica fume is an ultrafine material with spherical particles

less than 1 μm in diameter, the average being about 0.15

Because of its extreme fineness & high silica content,

silica fume is a very effective pozzolanic material.

Silica fume is also known as, Condense silica fume, micro

silica , silica dust.

Used Foundary sand

Used Foundary sand is used as a waste material

instead of Fine aggregate in concrete.

Metal foundries use large amounts of F.S. in the metal

casting process. Foundries successfully recycle and

reuse the sand many times in a foundry and the

remaining sand that is termed as used foundry sand

which is removed from foundry.

Use of used foundry sand in various engineering

applications can solve the problem of disposal of used

foundry sand.

This research focuses on studying the effect of used

foundry sand on the mechanical properties of concrete

mixtures as a partial replacement of natural fine

aggregate.

The successful use of industrial waste will aid in

reducing the environmental and health problems related

to the disposal of wastes and the scarcity of land area

needed for disposal.

By partially replacing both the material we can

produce structural grade Concrete.

In initial stage it gives later strength for the less silica

content, but if we remain constant the content of

silica fume and increase the content of used foundry

sand then strength is decrease by 7 %.

If we simultaneously increase the content of silica

fume and used foundry sand then there is increment

in compressive strength and it gives at earlier stage

by 7 days.

By comparing the compressive strength of two

material (Silica fume and Nano silica) we conclude

that cube with Nano silica content will give higher

strength as compare to cube with Silica fume.

Further in Nano silica, if we increase the percentage

of used foundary sand it will increase the strength of

concrete.
