An Experimental Study on Impact Strength of Self Compacting Concrete

Abstract

This project presents an experimental investigation on the main characteristics of Self compacting concrete properties in the fresh state like workability and mechanical properties of hardened self compacting concrete like compressive strength and impact strength .And also the determine mechanical properties of hardened conventional concrete like compressive strength and impact strength. The fly ash are replaced 20% in cement. To prevent the environment from noise and to make the work easy for the workers, self compacting concrete is used in this project .The ingredients used for SCC are 53 grade Ordinary Portland cement, Fine aggregate, Coarse aggregate, Super plasticizer, class-F Fly ash from Thermal power plant, Viscosity modifying agent. The basic properties of Cement, Fly ash, and Coarse aggregate, Fine aggregate are studied. The Mix design is carried out for approximately M30 grade of concrete by trial and error method. The Workability tests such as Slump Flow, V-Funnel, L-box, U-box test are carried out for self-compacting concrete. They slab was prepared on both self compacting concrete and conventional concrete by using weld mesh. The specimens for impact studies were tested by drop weight method. The slabs are tested at 7 and 28for self-compacting concrete and its impact test results are compared with Conventional M30 grade concrete.
