Effect of Fly Ash on Strength and Durability Parameters of Concrete

Siddamreddy Anil Kumar Reddy, Dr. K. Chandrasekhar Reddy

Abstract: Ordinary Portland cement (OPC) is one of the main ingredients used for the production of concrete and no alternative in the civil construction industry, and is a versatile and relatively high cost material. Large scale production of cement is causing environmental problems on one hand and depletion of natural resources on other hand. This threat to ecology has led to researchers to use industrial by products as supplementary cementations material in making concrete. The main parameter investigated in this study is M20 grade concrete with partial replacement of cement by fly ash by 0, 5, 10, 15and by 20 %. This paper presents a detailed experimental study on Compressive strength, split tensile strength, at age of 7 and 28 day. Durability study on acid attack was also studied and percentage of weight loss is compared with normal concrete. Test results indicate that use of fly ash in concrete has improved the performance of concrete in strength as well as in durability aspect.

Keywords: Fly ash, durability, Compressive strength, Split tensile strength, Acid resistance
