Recycle of waste Plastic Materials (Polyvinyl Chloride (PVC) and Polypropylene (PP)) as a fine Aggregates for Concrete

Abstract

The objective of this research is to investigate the effectiveness of using two types of waste plastic (Polyvinyl chloride (PVC) and Polypropylene (PP)) as sand aggregate replacement in concrete mixtures. Various concrete specimens were prepared and subjected to compressive tests to determine the effect of adding the two types of recycled plastic materials as fine aggregate replacement on the strength development of the mixes. Five mixes for each type of waste plastic were prepared different replacement percentages (and (10%, 15%,30%, 45% and 60 %) and compared. The comparison showed a noticeable increase in the compressive strength after 28 days when using PVC at 15% and 30%. The 15% replacement level showed 8.3% gain in compressive strength while 30% replacement level showed 3% gain in compressive strength. However, all the replacement percentages for PP showed noticeable decreases in compressive strength.
