Abstract

ABSTRACT - High-strength concrete is a material often used in the construction of high rise buildings. In the case of unexpected fire, the building concrete elements such as columns, slab and walls will be subjected to extreme temperatures. In order to assess the performance of high-rise concrete members it is important to understand the changes in the concrete properties due to extreme temperature exposure. The elimination of vibration for compacting concrete during placing through the use of Self compacting concrete leads to substantial advantages related to better Homogeneity, Enhancement of working environment and improvement in the productivity by increasing the speed of construction. This paper mainly concentrates on studying mechanical properties High Strength Self Compacting concrete subjected to Elevated Temperature of 200, 400 and 600oC with exposure duration of 4,8,12 Hours of Grade M80 Mix. The resulting concrete is characterized in the fresh state by methods used for Self compacted concrete, such as Slump flow, V-funnel and L-Box tests respectively
