Strength and abrasion resistance of concrete using plastic waste as partially fine aggregate replacement

Abstract

This research aims to study the effect of plastic waste as a partial fine aggregate replacement on compressive strength, flexural strength and splitting tensile strength and abrasion resistance of concrete. There were three types of plastic waste aggregate; polyvinyl chloride (PVC), polypropylene (PP) and polyethylene terephthalate (PET). Fine aggregate was partially replaced by plastic waste aggregate was at 10%, 20% and 30% by volume of fine aggregate. The water to binder ratio of 0.50 was used. The compressive strength, flexural strength, and splitting tensile strength and abrasion of concrete were evaluated. The study results found that concrete using plastic wastes (PVC, PP and PET) as partial fine aggregate replacement had lower compressive strength, flexural strength and splitting tensile strength than control concrete, but had higher the abrasion than control concrete with natural aggregate. An increase in fine aggregate replacement content with plastic waste decreased compressive strength, flexural strength and splitting tensile strength; conversely, it increased abrasion resistance.
