Experimental Study of Polypropylene and Bagasse Fiber as a Partial Replacement of Fine and Coarse Aggregate

Plastic is one of the most used materials in today’s world. Because of its non-biodegradable characteristics, it is obligatory to recycle the plastic in order to save the nature from its adverse effect. Plastic can be recycled by using it for construction purposes. This study aims at investigating the fresh and hardened properties of concrete while adopting polypropylene (PP) as coarse aggregate in concrete. Three concrete types were prepared with crushed stones as coarse aggregate and in two cases crushed stones were partially, 10% and 20% by volume, replaced with PP. Two water cement ratio, i.e. 0.45 and 0.55, were used in the concrete mix design. The usage of natural fiber in construction is 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%. Compressive 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 28day curing.
