It is a crystalline mineral composed of calcium sulfate dihydrate. Gypsum helps in controlling the rate of hardening of the cement. It also prevents early hardening allowing long working time, hence we can say that it helps in the rapid setting of cement
Gypsum is added to cement primarily to control its setting time. When cement is mixed with water, it starts to harden and set. Gypsum helps to regulate this process, preventing the cement from setting too quickly. This is crucial because it allows for better workability and more time to mix, transport, and place the cement before it begins to set. Without gypsum, the cement could set too rapidly, making it difficult to work with and potentially compromising the quality of the finished product.
