How To Do Cement Tests - Structural Guide

TESTING OF SOUNDNESS OF CEMENT. The ability of a hardened paste to retain its volume after setting is known as the soundness of cement. A cement is said to be unsound if it is subjected to delayed destructive expansion. The expansion could be due to hydration of uncombined calcium oxide and/or magnesium oxide.
