Indian Standard
SPECIFICATION FOR GRANULATED
SLAG FOR THE MANUFACTURE
PORTLAND SLAG CEMENT
0. FOREWORD
OF
0.1 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.
0.2 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. Portland slag cement may also be manufactured
by separately grinding Portland cement clinker, gypsum and granulated
slag and then mixing them intimately.
6.3 This standard contains clause 5.1 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.
0.4 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. SCOPE
1.1 This standard covers the requirements of granulated slag used in the
manufacture of Portland slag cement conforming to IS : 455-1976t.
2. TERMINOLOGY
2.0 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
2.1 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.
3. COMPOSITION
3.1 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.
3.2 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
5.5
Magnesium oxide
17.0
Sulphide sulphur 2.0
3.3 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
> 1.0
CaO+MgO+AlsOs
SiOZ
However, in case of slags containing more than 2.5 percent of man-
ganese oxide (MnO), the slag shall also satisfy
CaO + CaS+-l/2 MgO + Al,Os
SiOs+MnO
> 1.5
3.4 The insoluble residue of dried samples of granulated slag, determined
in accordance with IS : 4032-1985* shall not be more than 5 percent.
3.4.1 The glass content of granulated slag shall not be less than 85 per-
cent as determined by the method of optical microscope
Appendix A.
given at
*Method of chemical analysis of hydraulic cement (first nuision ).
4
IS t 12089 - 1987
4. SAMPLING
4.1 Granulated slag shall be supplied in. lots of 500 tonnes each. If the
quantity of slag delivered is less than 500 tonnes, it shall be considered
a lot.
4.2 Samples shall be drawn from at least five points of the wagon or truck
as the case may be. Each sample shall weigh about one kg.
4.3 The samples belonging to one lot collected as in 4.2, shall be thoroughly
mixed and a composite sample of 20 kg shall be collected.
4.4 The sample of 20 kg, obtained, as under 4.3, shall be divided into two
equal parts. One part shall be retained in a tightly sealed container for
future reference.
4.5 From the remaining portion ofthe slag sample, three samples of about
one kg each shall be drawn by methods of reduction and used for the
determination of moisture content adopting the procedure given in
Appendix B.
4.6 The remaining sample of slag, after drawing three samples as under
4.5, shall be air dried and blended thoroughly with the dry samples
obtained from 4.5 and tested for conformity with 3.1. The coarse and fine
fractions obtained in this test shall be blended again thoroughly and ground
to pass 150 pm IS sieve. The material obtained as above shall be treated
as the sample for all the tests under 3.2, 3.3 and 3.4.
NOTE -
In case the moisture content of the slag is not to be determined,4.5 may
be skipped and the entire material remaining after 4.4 shall be air dried and tested
for conformity with 3.1.
5. INSPECTION
5.1 The manner in which granulated slag shall be supplied should be
decided by agreement between the purchaser and the supplier. In case the
moisture content is to be determined, the method given in Appendix B
shall apply.
NOTE - The moisture content in granulated slag shall be as agreed to between
the purchaser and the manufacturer.
5.2 The manufacturer shall guarantee the conformity of the ~granulated
slag with the requirements of the standard and furnish each lot of supplied
slag with a certificate bearing the following:
a) Name and address of the manufacturer,
b) Certificate number and date of issue, and
c) Number of wagons containing the said lot.

IS t 12089 - 1987
5.2.1 If desired by the purchaser, the test results of the consignment
according to this standard shall also be supplied.
APPENDIX A
( Chse 3.4.1 )
METHOD OF TEST FOR GLASS CONTENT OF
GRANULATED SLAG
A-l. APPARATUS
A-l.1 Microscope - The microscope used for the purpose shall be
polarizing microscope used generally for the examination of thin sections,
and should have provision for mechanical stage and point counting. The
magnifying power of the microscope shall not be less than 100 x .
A-2. REAGENT
Ai2.1 Bromoform -
Bromoform shall be of A.R or G.R grade
chemical.
NOTE -
Any other liquid having refractive index between 1’5 to 1’6 may also
be used as an alternative to bromoform.
A-3. PROCEDURE
A-3.1 From about 5 g of a representative sample of powdered slag, a frac-
tion passing through 90 pm iS Sieve and retained on 52 pm IS Sieve shall
be treated as the sample for microscopic investigation as under A-3.2.
A-3.2 About one mg of powdered slag is placed on a rectangular glass
slide and a cover glass having its size less than the width of the rectangular
slide is placed on the material. One or two drops of bromoform or any
other suitable liquid ( see A-2.1 ) is added at the rim of the cover glass. It
is seen that the liquid enters between the cover glass and glass slide. A
gentle relative motion between the slide and cover glass shall be created to
disperse the material evenly in the immersion liquid. No attempt shall be
made to rub one slide over the other after the bromoform has been added.
The powder immersion section is examined with transmitted light under
the polarizing microscope at a magnification of about 200. About 1 500
grains are counted (JI,) by changing the field of view and traverses using
a mechanical stage with the help of cross-wire in the eye piece. Subsequcn-
tly under crossed nicols, the same field of view already scanned is examined
once again in similar fashion and grains which appear anisotropic and
opaque are counted (Jv,).

( Clauses 4.5 and 5.1 )
METHOD FOR DETERMINATION OF MOISTURE CONTENT
OF GRANULATED SLAG
B-l. APPARATUS
B-1.1, Drying Chamber - The air oven or other device such as an
infra-red moist determinator used for the purpose shall have adequate
chamber space to contain at least three samples of about one kg each of
granulated slag, when the material is spread in a metallic tray, with the
thickness of the material layer not exceeding 3 cm. The drying chamber
shall also have provision for temperature control at 110 f 5°C. The
drying chamber shall be an electrically operated unit.
-B-2. PROCEDURE
B-2.1 The mass of the three samples of moist granulated slag of about one
kg are determined, nearest to one g ( W1, W,, W’s). The samples are
spread separately in metallic rays of suitable dimensions such that the
thickness of the slag layer does not exceed 3 cm. The trays are kept in the
drying chamber maintained at 110 f 5”C, and retained there till the
mass of sample becomes constant nearest one g, as determined by periodic
weighing. The final masses of the dry samples are recorded as IV,, Wg, We
respectively.
B-3. CALCULATION
B-2.1 Calculate the moisture content of granulated slag as follows:
Moisture content, percent =
100x( w1+w2 +Ws)-( W,+W,+Ws)
