RESULTS FOR CEMENTITIOUS MATERIAL IN CONCRETE

Cementitious materials are one of the principal ingredients that make up the concrete mixture. There are two types of cementitious materials: hydraulic cement and supplementary cementitious materials (SCMs). Hydraulic cements set and harden by reacting chemically with water. During the reaction, which is called hydration, heat is given off as the …
