A Investigational Study on Partial Replacement of Coarse Aggregate and Fine Aggregate with Steel Slag and Eco-Sand

Now a days, Concrete is the 2nd highest using material in the world. In concrete we use all-natural materials like coarse aggregate, fine aggregate, water and binder which is called cement. Due to continuous utilization of coarse aggregate and fine aggregates for concrete we are facing different problems like lack of availability of these materials due to this the price of natural materials are increasing rapidly. To overcome this problem many researchers are finding the replacement for coarse aggregate and fine aggregate, through the study it is found that a by product of steel making called as steel slag having properties similarly to the coarse aggregate can be used as partial replacement of coarse aggregate, this steel slag is used because when the steelmaking process is going through Electric Arc Furnace(EAF) due to this process the steel slag have a strong strength properties. And Eco-Sand is a by product of ACC Cement which is manufactured in Coimbatore, Tamil Nadu. The Eco-Sand having micro particles due to this the mixture of concrete becomes strong and workable, due to very micro particles the eco-Sand fill the air voids in concrete and hence it gives better strength. Now using this two materials as partial replacement of carse aggregate and fine aggregate we form a new concrete. The main moto of project is to increase the strength of the normal concrete by replacing coarse aggregate to Steel Slag and fine aggregate to Eco-Sand. Here coarse aggregate is partially replaced to Steel Slag in 10%,20% and 30%, and fine aggregate is replaced to Eco-Sand in 25% permanently. After conducting various tests on replaced concrete we can conclude that replaced concrete gives high slump value, compression value ,flexural value and tensile value. For making concrete we used a M30 GRADE of concrete and all the results are noted and compared with the conventional concrete and thus the replaced concrete gives better compressive strength more than (30mpa) than conventional concrete, and flexural strength, tensile strength are noted, and studied. From the tests results a Particular mix of 30% of Steel Slag to coarse aggregate and 25% Eco-Sand to fine aggregate gives the maximum strength.
