Effect of Fly Ash and GBFS on Strength Parameters of Concrete

S. Saran Raj | Dr. K. Chandrasekhar Reddy ^[5]

Abstract: Concrete is widely used material for various types of structures due to its structural stability and strength. To reduce cost by using partial replacement of cement by fly ash and sand by GBFS it is economically better than normal concrete. And to reduce the volume of waste material from industries. By using these products in concrete it is safe in environment. Our aim is to study the properties of concrete by partially replacing cement by fly ash and fine aggregate (sand) by granulated blast furnace slag for m30 grade of concrete. Now in this project only 53 grade of cement is used. This paper reports comparative study on effects of concrete properties by partially replacement of OPC of 53 grade with fly ash and sand were partially replaced by blast furnace slag. The main variable investigated in the study of variation of fly ash dosage of 10 % and slag dosage of 10 %, 20 %, and 30 %. The compressive strength and split tensile strength of m30 grade of concrete was mainly studied. Test results shows that, inclusion of fly ash and GBFS generally improves the concrete properties up-to certain percentage of replacement in53 grade of cement
