Abstract

To enrich the properties of concrete and to study the performance of concrete polypropylene fiber and silica fume were used in this study. In this experimental work using of 2 different materials polypropylene fiber and silica fume fiber with different mix proportion of hybrid ratios to form the hybrid fiber reinforced concrete. silica fume and polypropylene fibers have altered properties and these properties will increases the flexural, tensile, impact strength of concrete. Shrinkage, Initial cracks can be resisted by using of polypropylene fibers. By this strength parameters also increases. In this work has been carried for M25 and M30 grade concrete according to IS 10262:2009 with five various proportions are added with concrete in gradients. The proportion of silica fume and polypropylene fiber is varying with different hybridization ratios i.e. 0%,0%, 1.0 %, 1.5% 2.0% and silica fume added by vol. of replacement of cement and polypropylene is added by the weight of cement. The tests were conducted on concrete such as slump cone test on fresh concrete, compressive test, flexural test, split tensile test and the modulus of elasticity on hardened concrete. These tests were done to analyze the hardened properties of concrete for 7& 28 days for compressive strength, 7 &28days for, split tensile strength, flexural strength. To evaluate the strength parameters different tests are conducted and results are tabulated. From experimental work and results it can be concluded addition of fiber gives maximum results in all the strength parameters compare to other different ratios.
