Cement Manufacturing Process :Part-10

Pounding the Clinker with Gypsum

The Cement Clinker is then air cooled. The required measure of Gypsum (5 %) is ground to the fine powder, and after that blended with the Clinker. At long last bond is gathered in packs and afterward transported to the required site.

Setting and Hardening:

At the point when common Portland bond is blended with water its synthetic compound constituents experience a progression of substance responses that make it set. These substance responses all include the expansion of water to the essential synthetic mixes. This compound response with water is called "hydration". Every one of these responses happens at an alternate time and with various rates. Expansion of every one of these responses gives the information about how Ordinary Portland bond solidifies and picks up quality. Those mixes and their part in solidifying of concrete are as under:

Tricalcium silicate (C3S): Hydrates and solidifies quickly and is generally in charge of introductory set and early quality. Normal Portland bonds with higher rates of C3S will display higher early quality.
