Abstract

Experimental work was performed to determine the compressive strengths of cylinder test and to compare them with various cement .Firstly we collect the ordinary Portland Cement, jute fiber, Sylhet sand, (3/4)" down stone chips, water, The primary objective of this study is to investigate the effect of reinforcing raw jute fibers on the mechanical properties of cement concrete composites. The investigation helps to explore more on the variation of properties of concrete with jute fibers, its effective usage and to reduce the usage of polymer fibers which interns an environmental harm. In the present study, raw jute fibers cut to 20 mm and 15 mm were used with the proportionate mix of cement, coarse aggregate and sand with the water cement ratio of 0.45. The mixed specimens are casted for different volume content of jute fibers (0%,0.1%, 0.5% and 0 .75%.) and 28 days. When 0.1% Jute using in concrete then the result of concrete compressive strength increase 5%. When 0.1% Jute using in concrete then the result of concrete tensile strength increase 7%
