GRANULATED BLAST FURNACE SLAG
Blast Furnace Slag is an industrial by-product for production of pig iron from iron ore in blast furnaces.
Molten Slag is cooled and dried by means of granulation so that it can be used as a bonding agent and
transformed into the amorphous phase.
The product activity of the granulated slag depends on the chemical structure of the amorphous phase,
and Granulated Slag, along with cement, behaves as a binder in cement production if it is ground at a
fineness of cement. The more active the slag is, the more resistant the concrete is.

GROUND GRANULATED BLAST FURNACE SLAG (GGBS)
If Granulated Blast Furnace Slag is ground at a fineness of 5000 – 6000 cm2
/g, so becomes a kind of
hydraulic binder, then it is called ground granulated slag.
FIELDS OF USE
Ground Granulated Blast Furnace Slag is used as a mineral additive for concrete production and
substitutes for cement. (TS EN 15167-1)
Slag cement can be used as the main additive. (TS EN 197-1)
Ground granulated blast furnace slag ensures that concrete has the following favorable features when it
is used as a mineral additive at particular proportions in concrete.
Fresh Concrete
Facilitates workability and settlement;
Increases impermeability;
Decreases water need;
Reduces shrinking when dried;
Decreases heat of hydration;
Slows down heat evolution;
Decreases density of concrete;
Enables use of coarse aggregate in larger amounts.
Hardened Concrete
Increases lifetime of concrete;
Increases ultimate resistance;
Increases strength development for the entire life of concrete;
Minimizes alkali-silica reactions in aggregate;
Increases resistance to aggressive environments (cid, sulfate, chloride);
Reduces thermal cracks;
Prevents diffusion of harmful liquids and gases;
Increases freeze-thaw resistance by means of its nonporous structure.
BLAST FURNACE SLAG CEMENT
Blast Furnace Slag Cement is a hydraulic binder, which is obtained by mixing portland clinker with some
limestone and ground granulated blast furnace slag (GGBS).
Blast Furnace Slag Cements are used in order to increase concrete strength, increase economic life and
protect the environment. If slag cement is used in concrete production more commonly, the amount of
CO2 emission in atmosphere will decrease and so dangerous impacts of greenhouse gases will be
reduced and the environment we live in will be healthier and areas on which natural agriculture is done
will broaden.
Slag Cement is designated as CEM III in the standard TS EN 197-1 and this cement has three sub-types
depending on the ratio of slag use (CEM III/A, CEM III/B, CEM III/C).
The slag ratios in these three types of cement are given in the following table.
Cement Type Ratio of Blast Furnace Slag (%)
Blast Furnace Slag Cement
CEM III/A min 36 – max 65
CEM III/B min 66 – max 80
CEM III/C min 81 – max 95
