Experimental Investigations on the Effective Utilization of Granite Powder in Self Compacting Concrete

M. Arunkumar, Dr. D. Padmini, S. Makeshkumar

Abstract: Concrete is most widely used construction material. Traditionally concrete is made up of cement, river sand as fine aggregate, crushed stone aggregate as coarse aggregate and potable water. Concrete has to be heavily vibrated for flow into very intricate forms or forms that have a lot of reinforcing bars. Hence to overcome these defects the self-compacting concrete is used. The self compacting concrete is a flowing concrete mixture that is able to consolidate under its own weight. The self compacting concrete flows easily at suitable speed into formwork without blocking through the reinforcement without being heavily vibrated. A well designed SCC mix does not segregate, has high deformability and excellent stability characteristics. River sand is one of the main ingredients used as a fine aggregate in concrete production. Nowadays, river sand is not readily available for use in many places. Instead of natural river sand, crusher sand or manufactured sand obtained from stone aggregate quarries is widely used as fine aggregate in concrete. Granite powder is a waste material obtained from granite processing industries. These materials have potential application as the replacement of fine aggregate in concrete. This study deals with the self compacting concrete where fine aggregate (M-Sand) is partially replaced with granite powder. Here M-Sand is partially replaced with 10 %, 20 % and 30 % of granite powder. Experimental work on various proportions of concrete mixes was done and the Fresh and Hardened properties of self compacting concrete are obtained.
