Abstract

Cement based materials are quasi-brittle and are known to exhibit a highly stress-rate sensitive behavior. In structures that are subjected to impact forces, this causes concern in two ways: first the brittleness may result in catastrophic failure without warning and second, the properties of concrete during such events may be very different from those measured in standardized quasi static tests. Unfortunately, there are no standardized tests available for testing concrete under impact loading and there is significant confusion as to what constitutes an appropriate test. Concrete is a mostly used construction material in the world. As the use of concrete becomes wide spread the specifications of concrete like Durability, Quality, Compactness and Optimization of concrete becomes more important. Self Compacting Concrete (SCC) is a very fluid concrete and a homogeneous mixture that solves most of the problems related to ordinary concrete. Besides, SCC gets compacted under its own weight and there is no need for an internal vibrator for the body of the mould. This specification helps the execution of construction components under high compression of reinforcement. This paper concentrates mainly on studying the properties like workability and Impact strength of Fibre Reinforced High Strength Self Compacting concrete using Steel Fibres in various proportions ranging from 0 to 1.5 % for SCC mixes of Grade M 80.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.
