An Experimental Study on Hybrid Fibre Reinforced Concrete Containing Nano Alumina and Metakaolin

Abstract

The paper presents the results of research study carried out on ternary blended concrete containing Nano Alumina (NA), Metakaolin (MK) and Hybrid fibres (Polypropylene & Glass fibres). The optimum combination of nano alumina and metakaolin has been arrived at using standard procedures from the point of view of mobility and strength. The optimum combination has been found to be 1% nano alumina and 15% metakaolin. Fibreshave been added in 0.3% volume fractions at different ratios (70% PP&30%glass, 60% PP& 40%glass, 50% PP& 50%glass, 40% PP& 60%glass, 30% PP& 70%glass) to examine theirimpact on the mechanical properties of concrete involving nano alumina, metakaolin. Compressive Strength, Flexural Strength and Elasticity Modulus for the above concrete mixtures have been found using appropriate specimens such as cube, cylinder and prism following the standard test protocols.
