Structural behaviour of bagasse Ash concrete exposed to different environmental conditions

Abstract

In case of sudden fire, the concrete elements such as beams, columns etc will be subjected to extreme temperatures and need for assessment of their performance after fire. Hence, it is important to understand the change in the concrete strength properties due to extreme temperature exposure. In this study bagasse ash is used as partial replacement of cement because it is one of the by product which can be used as mineral admixture due to its high content in silica (SiO2), it is also a waste product produced from Sugar manufacturing industry. In this study sugarcane Bagasse ash partially replaced in the ratio of 0%, 5%,10%,15% and 25% by weight of cement in concrete and exposed to different elevated temperature (i.e 2000, 4000, 6000, 8000 ) for 1 hour and immediately cooled with water. The result shows that the strength of Concrete specimens increased at 2000C than room temperature for all percentage of replacement of cement with SCBA.
