Abstract
Concrete is globally used material. Concrete is good at compression and bad at tension so we are using the different types of fibers to improve the tensile properties. Now a days we are using both metallic and non-metallic fiber reinforced concrete material like glass, steel and sisal fibers. Sisal fiber is added to the concrete with different Aspect Ratios are 50, 75,100. The weight of sisal fiber based on weight of cement in concrete mix in M30 grade concrete. The Compressive strength of Concrete optimum at 50 A.R with 1.5 % which is 11.5% more than average compressive strength without fiber. The Split tensile strength of Concrete optimum at 50 A.R with 1.5 % of sisal fibre by the weight of cement which is 20.64% more than average concrete strength without fiber. The Flexural strength of Concrete optimum at 50 A.R with 1.5 % of sisal fibre by the weight of cement which is 7.092% more than average concrete strength without fiber. The main drawback in this study is more the sisal fiber the workability less.
