Investigation of Abrasion Test and Mechanical Properties of Concrete Using Fly Ash as A Partial Replacement of Cement

Abstract

Abstract: Concrete is one of the most versatile and widely used material in the construction sector. With the development and advancements of concrete, Civil engineering has reached its technological pinnacle. Despite its global and excessive demands, the consumption of cement is increasing day by day which is to be managed. Also there are many challenges related to its consistent strength performance , Abrasion resistance, Durability etc. so there is a great need to overcome these problems by the application of a pozzolanic admixture known as Fly ash which is responsible for improving various mechanical properties of concrete such as Abrasion Resistance and strength aspects and also reducing the consumption of cement at the same time. In this experimental Work, the Inclusion of Fly Ash and its effect on the various mechanical properties of the concrete i.e. Abrasion resistance, compressive strength, split tensile strength and flexural strength etc is investigated. The present investigation is carried on M35 Grade concrete. Firstly, concrete mixes is prepared by using Ordinary Portland cement( OPC 53) as a reference concrete mix and then blended concrete mixes is prepared by partial replacement of cement using fly ash in range of 10%, 20%, 30%, 40%, 45% by the weight of cement. This experimental study is carried for Determining the differences in the various mechanical properties of blended concrete (Fly ash and cement) and conventional concrete. The optimum percentage of using fly ash with cement in the concrete mixes is determined. The various parameters studies of concrete investigated are Abrasion resistance , workability of freshly prepared concrete mixes, compressive strength at 7 and 28 days, split tensile strength at 28 days. All these tests on concrete mixes is to be performed for both conventional concrete mixes (using only OPC) and also with blended concrete mixes ( OPC and its partial replacements with fly ash).
