Experimental Study on Sfrm Concrete

Abstract

Cement concrete is the mostly used material for various constructions. Concrete has good strength and durable properties. The main ingredient in the conventional concrete is Portland cement. Cement production is consuming a significant amount of natural resources. The ill effect the advent of newer materials and construction techniques and drive admixture has taken new things and it has become necessity for future. The use of new mineral admixtures has considerably increased within the concrete industry for attaining a high strength, durable concrete for major applications in the constructions such as high rise buildings, tall structures, nuclear power plants etc. The essential need of additives both chemical and mineral is must to improve the performance of concrete. Plain concrete possesses very little tensile strength, limited ductility and little resistance to cracking, hence this present study use of Metakaolin  and  hook ended steel fiber reinforced concrete into ordinary cement concrete. In this experiment metakaolin at various percentages as 0%, 5%, 10%, 15%, 20% by weight of cement and steel fiber content of 0%, 2.5%, 5%, 7.5% and 10% is used. It also includes the effect of aggregate size on strength of concrete 6mm, 10mm, 12mm aggregate sizes are used throughout the experimental work. In this experiment various mechanical properties of concrete like compressive strength, split tensile strength, flexural strength were observed at the age of  28 days of curing. In experimental results of compressive strength, flexural strength & flexural deformation of FRM are compared with FE results using ANSYS.
