Abstract

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. 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 The resulting concrete is characterized in the fresh state by methods used for Self compacting  concrete, such as slump-flow, V-funnel and L- box tests respectively.

Cement based materials are quasi-brittle and are known to exhibit a highly stress-rate sensitive behaviour. In structures that are subjected to impact forces, this causes concern in two ways: first the brittleness may result in catastopic failure without warning and second, the properties of concrete during such events may be very different from those measured in standardized quasistatic tests. Unfortunately, there are no standardised tests available for testing concrete under impact loading and there is significant confusion as to what constitutes an appropriate test. This paper presents an experimental investigation on the compressive strength and impact resistance of glass fibre self compacting concrete using Alkali-Resistant Glass Fibres for various grades of concrete mixes of M 30 to M 65.
