Dry granulation of cement under pressure is not a viable option as the powder cannot be simply compressed into a solid. wet granulation involving the use of a binder, is possible, but it significantly reduces the activity of the cement as any water absorbed starts the irreversible chemical reaction that turns cement into concrete.

Among the emitted radionuclides, cesium137 (137 cs, t 12 30.2 y) has been widely studied because of its long halflife and its large amount emitted to the environment.

Summary: due to the necessity to reduce co 2 emissions in cement making the partial substitution of cement clinker by granulated blast furnace slag (gbfs) has become established. this article deals comprehensively with the granulation process of gbfs as well as with the effects of the granulating process on the properties of gbfs.
