cementitious material in concrete Topic
2024年11月22日 · 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 water-cement paste hardens and binds the aggregate particles together.

Definition of concrete, hydraulic cement, mortar, and grout
A. Concrete is a composite material that consists of a mixture of hydraulic cement, aggregates, and water, with or without admixtures, fibers, or other cementitious materials. Hydraulic cement is cement that sets and hardens by chemical reaction with water (hydration) and is capable of doing so under water (ACI 225R). The hydration reactions ...
