Experimental Analysis of Asbestos Fibre Reinforced Concrete Composite

Abstract

All countries are focusing on sustainable technology that can be economical and adopted for the use of concrete in a better way. Concrete is most widely used construction material and it possesses very low tensile strength, low shear strength and brittle characteristics. In order to improve these properties a relatively new construction material developed through extensive research and development work called Fibre Reinforced Concrete (FRC). An attempt has been made to analyze the effect of addition of asbestos fibre in ordinary portland cement concrete at their optimum proportions. To determine the properties concrete compressive strength and flexural strength test were performed at different test age like 7, 14 and 28 days. M 30 grade concrete was designed as per IS 10262-2009. The additions of fibre were varying from 0.33%, 0.66%, 1.0%, 1.33%, 1.66% and 2.0% by volume of concrete for AFRC. The maximum compressive strength of AFRC obtained at 0.33% addition of fibre. Test results shows that the compressive strength of AFRC marginally improved, but there is a significant improvement in the flexural strength.
