Strength loss contributions during stages of heating, retention and cooling regimes for concretes
Subhash C. Yaragal, Jishnu Warrier and Ramesh Podila
Abstract
Concrete suffers strength loss when subjected to elevated temperatures during an accidental event such as fire. The loss in strength of concrete is mainly attributed to decomposition of C-S-H gel and release of chemically bound water, which begins when the temperature exceeds 500
Key Words
