Concrete, the most common construction material which has less tension capacity. And, a light weight concrete has many application in construction industry now a days due to its provision of less dead load, improvement for seismic structural response, suitability for transporting, and handling economically. Reinforcing material such as natural fiber, can be used to increase crack control and ductility by reducing the tendency of brittleness of concrete. The objective of this study was to evaluate the density, and tensile strength with its correlation with compressive strength of normal weight and lightweight concrete produced when incorporating with sugarcane bagasse fiber. The study has great significance in developing new advanced concrete product which has reduced density and high ductility with reduced crack. Furthermore, the usage of sugarcane in construction can reduce of environmental pollution. Sugarcane fibers extracted from bagasse by manually was used in volume fraction of 0%, 0.5%, 1.0%, and 1.5% in terms of weight of cement in mix with average fiber length of 25mm. In this study, lightweight aggregate (scoria) was used by replacing the normal weight aggregate by 50% and semi-lightweight concrete achieved. In order to obtain the output of the objective of the study, total of 48 cubes, 48 beams, and 48 cylinder specimens was prepared, and the tests performed on 7th and 28th days curing period. As result of the testing showed that the increase of fiber decreased the unit weight of concrete with light weight aggregate, but it is not uniform for normal weight concrete. The optimum value containing addition of sugarcane bagasse fiber is 0.5% due to flexural and split tensile strength with a little impact on compressive strength. Therefore, the use of sugarcane fiber in concrete is suitable for addition that do not exceed 0.5% of the concrete mixture.
