Abstract

Light weight Concrete (LWC) is the most common material for human beings to use in construction. In this study, the effect of the waste plastic fiber on the strength and durability of lightweight concrete has been investigated. Lightweight concrete contains polyethylene terephthalate (PET) plastic fiber obtained from a waste plastic bottle. The reason for choosing PET bottles is to solve environmental pollution as a result of dumping the tons of plastic waste by developing a novel method of transferring it into a valuable product. The main objective of this investigation is, therefore, to compare the strength of hardened lightweight concrete containing plastic fiber with control mix of lightweight concrete. In this investigation, the strength of M30 lightweight concrete has been taken. In addition, workability tests such as slump test, compaction factor test and vee-bee consistency tests were conducted on the fresh concrete. Moreover, compressive strength, tensile strength, flexural strength and water absorption tests were evaluated to determine the strength properties of hardened lightweight concrete. A finding of the study shows that workability, compressive strength and water absorption has increased by addition of waste plastic fiber. To improve strength performance, the weight of plastic fiber added to the lightweight concrete is 1% of the weight of the cement the results are compared and conclusions are made.
