Evaluation of the use of blast furnace slag as an additive in mortars

Clinker is the raw material used in manufacture of cement. However, this very harmful to environment, since it estimated that for every ton clinker produced, about 1.0 CO2 released into atmosphere. For reason, alternatives were sought use other materials are less environment. This has led industrial by-products with aim increasing their and thus reducing amount carbon Blast furnace slag a by-product some cementitious products. The research conduct study on as an additive cement or concrete. mortar samples tested according Brazilian, American European technical standards. Physical, chemical compressive strength tests carried out which confirmed possibility using without thermal activation.
