Abstract :

High strength self compacting concrete is a fluid mixture suitable for congested reinforcement. It should posses a good balance between the deformability and suitability. This is being used in increasing volume in recent years due to its mechanical properties and durability properties than conventional concrete. In this paper the High strength self compacting concrete with different minerals used and their performances were presented. By adding admixtures like silica fume, and quarry dust will decrease the flow ability, to improve this super plasticizers were added. The successful utilization of silica fume and quarry dust could turn this waste material into valuable resources. As per EFNARC guidelines the fresh concrete properties of the trial mixes checked and the one which gives the maximum strength has been used in the present work. Slump flow, V-funnel, U-Box L-Box tests are checked against the specifications given by EFNARC guidelines for qualifying self compacting properties. This project presents the results of mechanical and durability properties of high strength self compacting concrete (HSSCC) with silica fume, quarry dust and super plasticizer. Thus, the improvement in durability properties of a concrete mix having partial replacement Silica Fume (SF) of 20% and Quarry Dust (QD) of 20% was found to be the best. SEM Analysis was done for normal concrete and HSSCC samples and it was displaying silica fume and quarry dust formation with concrete gives non porous medium and arrest the cracks. Also it resists the water and air environment and improves the strength.
