Oct 04, 2018 Cement is a commonly used binding material in the construction. The cement is obtained by burning a mixture of calcareous calcium and argillaceous clay material at a very high temperature and then grinding the clinker so produced to a fine powder. It was first produced by a mason Joseph Aspdin in England in 1924. He patented it as Portland cement.

Having a higher percentage of C 3 A, cement sets quickly, and releases a high heat of hydration. C 3 S gives the cement its initial strength, and makes it harden rapidly. On the other hand, C 4 AF has little to do with strength, but imparts the gray color to ordinary Portland cement. Heat of hydration is the term used to describe the heat released when cement reacts with water during the ...
