C3S (Tricalcium silicate)

C3S, or tricalcium silicate, is a primary component of Portland cement. When mixed with water, it reacts to form calcium silicate hydrate and calcium hydroxide, leading to cement's hardening process. This chemical reaction releases heat and gives concrete its strength and early setting properties. Essentially, C3S is responsible for the initial strength development in concrete and influences how quickly it gains hardness. Its efficient performance ensures durable, strong structures when used in construction.
