An Experimental Investigation on M30 Concrete with Partial Replacement of Fine Aggregate by GBS

Abstract

Now a days construction material is more important in utilization of world . At present there are three materials are more important they are cement , coarse aggregate & fine aggregate . At present lack of utilization materials ,the raw materials of construction is less compare to the other materials .Our project deals with the replacement of fine aggregate by GBS (Granulated blast furnace slag ) by 0% , 5 % , 10 % , 15 % , 20 % .As this percentage to increase the strength of concrete . Granulated blast furnace slag is less than 4.7mm is used. GBS is a by-product of the steel industry . It is defined as the non-metallic product consisting essentially of calcium silicates and other bases that is developed in a molten blast furnace slag is durable. Due to the consistent shape & volume the construction is safe. Indian construction companies have initiated the use of slag as replacement of sand where as in countries like brazil & japan have an established market. The granulated blast furnace slag is produced after the material is treated of about 1500 degrees celsuis , the material will be safe to use as chemicals in it becomes inert .
