Different Types Of Cement and Their Uses In Construction

The following types of cement are used in Construction. 1. Acid-Resistant Cement: Acid-resistant cement is composed of the following: (i) Acid-resistant aggregates such as quartz, quartzites, etc. (ii) Additive such as sodium fluosilicate Na2 SiF6; and (iii) Aqueous solution of sodium silicate or soluble glass. The addition of additive sodium fluosilicate accelerates the hardening process of soluble glass and it [...]
