Cement substitutes provides a way for reusing of byproducts from different industrial processes like slag and many others. c. The materials used as cement substitutes conserve energy as compared to cement as they require less energy for repurposing.
Cement Alternatives
The use of SCMs reduces the quantity of clinker or cement required. They are added to cement either at the grinding stage or by blending with cement after grinding; or can be added during concrete batching to supplement the cement. Because of differences in chemistry, SCMs affect the performance of cement in concrete to suit different applications.
