Study on Mechanical Properties of Hybrid Fibre Reinforced Concretes

In this study aims to characterize and quantity of the mechanical property of hybrid fibre reinforced concrete. The using of hybrid concrete like coir fibre and jute material are adding and cement replacing with some proportion of ground granulated blast furnace slag (GGBS). Coconut or coir fiber and jute are naturally available materials at low cost. The tests on hybrid fiber reinforced concrete are compressive strength test, flexure, and tensile tests. By mixing and casting of concrete, the fibers are add with 0.5%, 1%, 1.5% and fibre length are 2cm. The test on concrete cubes is compressive test, on cylinders tensile test and on beams flexure test. The curing of cubes, cylinders and beams is 7, 28 and 90-days. The composite hybrid means that the two or more types are combined with rationally proportion and its benefits to mass concrete. Mostly fibers are added to increase flexure strength and tensile then it also affects the coir fiber and jute. But in the so many researchers, the adding of this material increases the flexure and tensile strength, decreases the compressive strength.
