SPECIFICATION FORCHEMICAL RESISTANT MORTARSPART III SULPHUR TYPE

0. FOREWORD0.1 This Indian Standard was adopted by the Indian Standards Institutionon 17 November 1968, after. the draft finalized by the Flooring andPlastering Sectional Committee had been approved by the Civil EngineeringDivision Council.0.2 Sulphur mortars have good resistance against most of the acids exceptconcentrated oxidizing acids, but have very poor resistance to alkalies.Sulphur mortars are used for jointing acid resistant bricks or tiles in floors,~ in the lining of storage tanks, pickling tanks, sumps, drains, etc. Specialcare shall be taken that sulphur mortar is not overheated during theheating process. For the actual method of use of sulphur mortars,IS : 4442-1967* may be referred.0.3 In the formulation of this standard due weightage has been given tointernational co-ordination among the standards and practices prevailing indifferent countries in addition to relating it to the practices in the field inthis country. This has been met by deriving assistance from C287-1962 Standard Specifications for sulphur mortars issued by the AmericanSociety for Testing and Materials.0.4 Investigations carried out by the Central Building Research Institute,Roorkee, has also been of assistance.0.5 This standard is one of a series of Indian Standards on chemicalresistant mortars. Other standards published so far in the series are:

IS : 4441-1967 Code of practice for use of silicate type chemicalresistant mortarsIS : 4442-1967 Code of practice for use of sulphur type chemicalresistant mortarsIS : 4443-1967 Code of practice for use of resin type chemical resistantmortarsIS: 4456 (Part I )-1967 Methods of test for chemical resistantmortars: Part I Silicate type and resin typeIS : 4456 ( Part II )-1967 Methods of test for chemical resistant

mortars: Part II Sulphur type*Code of practice for use of sulphur type chemical resistant mortars.3

IS: 4832 (PartHI) - 19680.6 For the purpose of deciding whether a particular requirement of thisstandard is complied with, the final value, observed or calculated, expressingthe result of a test or analysis, shall be rounded off in accordance withIS : 2-1960. The number of significant places retained in the, roundedoff value should be the same as that of the specified value in this standard.

1. SCOPE1 .l This standard covers the requirements of sulphur type chemical resistantmortars for bonding chemical resistant masonry units.2. TERMINOLOGY2.0 For the purpose of this standard, the following definition shall apply.2.1 Sulphur Type Chemical Resistant Mortars - It is an inorganiccompound consisting of an intimate mixture of sulphur and inert filler, suchas silica. Small amounts of chemically-resistant inert modifying agentsmay be added.3. CHEMICAL COMPOSITION3.1 The sulphur mortar shall conform to the following requirements forchemical composition:

Sulphur 55 to 70 percentInert filler 30 to 45 percent3.1.1 The sulphur content of the sulphur mortar shall be determinedaccording to the procedure laid down in 8 of IS : 4456 ( Part II )-19671_.

3.2 On a. sieve analysis of the filler the percentage material retained ondifferent sieves shall not exceed the following:I S Si eve Desi gnat i on Per cent age M ateri al Retai ned

425-micron IS Sieve 5.0 M ax150-micron IS Sieve IO.0 M in75-micron IS Sieve 3.50 M in

3.2.1 If required by the user, the manufacturer shall give a certificatethat the filler conforms to the grading specified in 3.2.4. PHYSICAL REQUIREMENTS4.1 The sulphur mortars shall satisfy the requirements given in Table 1when tested in accordance with IS : 4456 ( Part II )-19677.

8.2.1 Each package may also be marked with the Standard Mark,NOTE - The use of the Standard Mark is governed by the provisions of theBureau of Indian Standards Act, 19Y6 and the Rules and Regulations made there-under. The Standard Mark on products covered by an Indian Standard conveysthe assurance that they have been produced to comply with the requirements of thatstandard under a well defined system of inspection, testing and quality controlwhich is devised and supervised by BE and operated by the producer. Standardmarked products are also continuously checked by BIS for conformity to that

standard as a further safeguard. Details of conditions under which a iicence forthe use of the Standard Mark may be granted to manufacturers or producers maybe obtained from the Bureau of Indian Standards.
