FOREWORD OF This Indian Standard was adopted by the Bureau of Indian Standards on 27 May 1987, after the draft finalized by the cement and Concrete Sectional Committee had been approved by the Civil Engineering Division Council. granulated slag is used for the manufacture of hydraulic cement by mixing portland cement clinker, gypsum and granulated slag in suitable proportions and grinding the mixture to get a thorough and intimate mix between the constituents.

8 portland slag cement may also be manufactured by separately grinding portland cement clinker, gypsum and granulated slag and then mixing them intimately. This standard contains clause which calls for agreement between the purchaser and the supplier regarding the manner in which granulated slag shall be supplied and whether moisture content is to be determined. For the purpose of deciding whether a particular requirement of this standard is complied with., the final value, observed or calculated, expres- sing the result of a test or analysis, shall be rounded off in accordance ~with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard, 1.

9 SCOPE This standard covers the requirements of granulated slag used in the manufacture of portland slag cement conforming to IS : 455-1976t. 2. TERMINOLOGY For the purpose of this standard, the following definition shall apply. *Rules for rounding off numerical values ( revised ). * Specification for portland slag cement ( third revision ). 3 IS : 12089 - 1987 granulated Slag - Slag is a non-metallic product consisting essenti- ally of glass containing silicates and aluminates of lime and other bases, as in the case of blastfurnace slag, which is developed simultaneously with iron in blastfurnace or electric pig iron furnace. granulated slag is obtain- ed by further processing the molten slag by rapidly chilling or quenching it with water or steam and air.

10 3. COMPOSITION The physical state of aggregation of granulated slag shall be in the form of granules. The proportion of lumps exceeding 50 mm size shall not constitute more than 5 percent of the mass of slag. When tested in accordance with the methods given in IS : 4032-1985*, the composition of granulated slag shall comply with the following chemi- cal requirements: Constituent Percent, Max Manganese oxide Magnesium oxide Sulphide sulphur The percentages of major oxides in the granulated slag, determined in accordance with the methods given in IS : 4032-1985*, shall satisfy at least one of the following: CaO+ MgO+ l/3 AleOs SiO,+2/3 AlsOs > CaO+MgO+AlsOs SiOZ However, in case of slags containing more than percent of man- ganese oxide (MnO), the slag shall also satisfy CaO + CaS+-l/2 MgO + Al,Os SiOs+MnO > The insoluble residue of dried samples of granulated slag, determined in accordance with IS.
