Abstract :
Self compacting concrete is a development of conventional concrete, in which the use of vibrator for compaction is no more required. But its initial higher supply cost over conventional concrete, has hindered its application to general construction. Therefore, for producing low cost SCC, it is prudent to look at the alternates to help reducing the SSC cost. This research is aimed at evaluating the usage of bagasse ash with viscosity modifying agent in SCC, and to study the relative costs of the materials used in SCC. The normal concrete is weak in initial shrinkage where as introduction of fibers to concrete decreases its initial shrinkage and also imparts higher strength to concrete later on stage. In this project a study has been done on replacement of cement with bagasse ash and the effect of Polypropylene fiber on the hardened properties of SCC like compressive, split tensile and flexural strength. The SCC made with varying percentage of bagasse ash from 10% to 20% and Polypropylene fibres from 0% to 0.2% to the total volume of concrete along with addition of viscosity modification agent 0.3% to the volume of cement content for M30 mix proportion. The main focus of this study will be on investigating maximum percentage replacement of bagasse and Polypropylene Fiber that can be added to total volume of concrete to attain maximum value of both compressive and flexural strength and to study the flexural behavior of beams with reinforcement.
