PARTIAL REPLACEMENT OF CEMENT WITH FLY ASH WITH THE ADDITION OF STEEL FIBERS

Concrete's structural stability and strength make it the most often utilised building material in the civil engineering sector. Directly releasing garbage into the environment might have negative effects on the environment. The importance of recycling waste has thus been highlighted. To use natural resources more effectively and preserve the environment from waste deposits, waste can be used to create new goods or used as admixtures. The fine powder left over after burning pulverised coal is called fly ash. It is a type of waste material, and in order to make use of it, the fly is combined with steel fibres and added to concrete. The dissertation is completed by utilising m25 grade concrete with cement replacing 10%, 20%, and 30% of the fly ash along with the addition of 0.5% and 1% steel fibre to the concrete's total weight. The goal of the study is to determine the ideal replacement and addition rate of steel fiber for achieving the highest compressive strength. There are numerous reuse and recycling options for this industrial by-product, both in the experimental stage and in actual applications.
