Properties of Sugarcane Fiber on the Strength of the Normal and Lightweight Concrete

The usage of natural fiber in construction are widely used in building materials engineering. However, using sugarcane fiber waste material as a natural in construction is very precious, because it can increase crack control and ductility, brittle concrete. Furthermore, the usage of sugarcane in construction can reduce of environmental pollution.In this study, a mixture of sugarcane fiber to be used in normal grade concrete and lightweight concrete to determine whether there is an increase in the compressive and tensile strength of the concrete. The objective of this study was to determine the compressive and tensile strength between control concrete and concrete mix with sugarcane fiber. In addition, the optimal volume of sugarcane fiber in the concrete mixture where the percentage of sugarcane fiber used was 0.5%, 1.0% and 1.5%. Compessive strength was tested on days 7 and 28 after curing test is carried out. Meanwhile, the tensile test, has been carried out to measure the tensile strength of sugarcane fiber relations in concrete mixes only at 28 day curing. Result of the testing showed that the optimum value containing admixtures of sugarcane is 0.5%. This percentage get the value of compressive strength is nearest with concrete control and the value of tensile strength is higher than concrete control and also the timing of concrete to cracked getting slower. Therefore, the use of sugarcane fiber suitable for addition that do not exceed 0.5% of the concrete mixture
