An Experimental Analysis on Mechanical Properties of Concrete with Polypropylene Woven Fibre Including Admixture with Fly Ash as a Partial Replacement of Cement

Abstract

Fibre Reinforced Concrete can be defined as a composite material consisting of mixtures of cement, mortar or concrete and discontinuous, discrete, uniformly dispersed suitable fibres. The synthetic fibres available in the United States, polypropylene is the most widely used in ready mixed concrete. The combinations of fly ash concrete with fibre reinforcements to enhance the mechanical properties. Addition of polypropylene fibre was found to improve the durability of concrete composites containing fly ash. Admixtures are generally used to alter the properties of concrete (such as increased workability or reduced water content, acceleration or retardation of setting time, acceleration of strength development, and improved resistance to weather and chemical attacks) to make it more suitable for a particular purpose. In this paper an experimental analysis has been carried out to show the impact of Polypropylene Woven Fibre including Admixture with different quantity of Fly Ash as a partial replacement of cement on flexural strength and split tensile strength of concrete cubes for M-30 grade of concrete mix. It is found that flexural strength and split tensile strength has been increased by using 5% & 10% PPWF including 5% Admixture with 10%, 20% and 30%Fly Ash as a partial replacement of cement.
