SAXENA (Alternate)SUPERINTENDING ENGINEER (DESIGNS)Public Works Department, Government ofTamil Nadu, MadrasEXECUTIVE ENGINEER (SMD DIVISION) (Alternate)(Continued on page 41 ) IS : 4032 19853 Indian StandardMETHOD OF chemical analysis OF hydraulic CEMENT( First Revision ) O R E W O R Indian Standard (First Revision) was adopted by the IndianStandards Institution on 30 October 1985, after the draft finalized bythe Cement and Concrete Sectional Committee had been approved bythe Civil Engineering Division methods of testing cement are essential adjuncts to thecement specifications because faulty test methods may lead toerroneous conclusions as to the quality of cement.

7 The Cement andConcrete Sectional Committee has, therefore, formulated methods ofchemical and physical tests of hydraulic cements in details in twoseparate standards which could be referred to in each of thespecification for different types of hydraulic cement. This standardcovers methods of chemical analysis of hydraulic cement whilemethods of physical tests are covered in IS : 4031-1968*. standard was first published in 1968. A need has been felt tointroduce rapid methods of chemical analysis of cement to cut downthe time taken for determination of major constituents. In thisrevision, therefore, rapid complexometric (EDTA) methods developedby National Council for Cement and Building Materials have beenincluded as alternate methods for estimation of CaO, MgO, Fe2O3 andAl2O3 in ordinary and low heat Portland cement, rapid hardeningPortland cement, Portland slag cement and Portland pozzolanacement.

8 In case of dispute or doubtful marginal values, thegravemetric methods for estimation of CaO, MgO and Al2O3 andpotassium permanganate Method for estimation of Fe2O3 shall betaken as referee Method . For rapid complexometric methods ofanalysis, photometric end point detector shall be used for betterdetection of sharp end point where sufficient skill is not edition incorporates Amendment No. 1 (May 1998). Sidebar indicates modification of the text as the result of incorporation ofthe amendment.*Methods of physical tests for hydraulic cement. IS : 4032 the purpose of deciding whether a particular requirement ofthis standard is complied with, the final value, observed or calculated,expressing the result of a test or analysis , shall be rounded off inaccordance with IS : 2-1960*. The number of significant placesretained in the rounded off value should be the same as that of thespecified value in this standard gives the procedure for the chemical analysis of thedifferent types of hydraulic addition to the tests for chemical requirements prescribed indifferent cement specifications, this standard also covers test fordetermination of free lime in Portland cement, pozzolanicity test forPortland pozzolana cement and staining test for masonry analysis of hydraulic cement may be done using rapid methods such as atomicabsorption spectrophotometer Method (see IS : 12813-1989 ) or X-ray fluorescencespectrometer Method (see IS : 12803-1989 ), or calorimetric analysis (seeIS : 12423-1988 ) not covered in this standard.

9 However, in case of dispute or doubtfulmarginal values, the Method given in this standard shall be taken as referee samples of the cement shall be taken as per requirements ofIS : 3535-1966|| and the relevant standard specification for the type ofcement being tested. The representative sample of the cement selectedas above shall be thoroughly mixed before REPRODUCIBILITY OF determinations shall be made on the reagents for eachconstituent in the cement and the corrections shall be applied wherenecessary. In all cases check determinations shall be made andrepeated if satisfactory checks are not obtained. The differencebetween check determinations shall not exceed percent for silicaand alumina, and percent for other difference between check determinations by EDTA methodshall not exceed percent for calcium oxide and magnesia, for alumina and percent for ferric oxide.
