Experimental Study on Use of Fly Ash as a Partial Replacement of Cement in Concrete

Santosh Kumar, Anuj Verma

Abstract: Cement ranks high among the world's most popular construction materials. A major contributor to the recent spike in carbon emissions is the cement industry. Partial cement substitutes made of alternative or low - emissions binders have grown in popularity in the last several years. The inexpensive cost and large annual production of fly ash as a waste material have made it one of the most accessible options. Due to their low cost and outstanding performance, fly ash - based building materials show great potential as alternatives to cement. This article delves into the ways in which fly ash impacts the practicability, setting time, compression strength, and tensile strength of concrete. Additionally, the types and properties of fly ash were examined.
