Waste Plastic Aggregates as a Replacement of Natural Aggregates

Abstract

The construction industry is the biggest purchaser of natural aggregates which prompted exhaustion of good quality regular sand (fine aggregates). Stream sand, which is one of the constituents utilized as a part of the creation of ordinary concrete, has turned out to be exceptionally costly and furthermore rare. In the setting of such a depressing climate, plastic aggregates can be used beneficially. In this investigation, the reused plastics were utilized to set up the fine aggregates along these lines furnishing an economical alternative to manage the plastic waste. During this study waste Polythene Terephthalate (PET) heated to make PET agglomerate, then cooled and crushed into aggregates that embrace sort of sizes with definite gradation. The different concrete mixes were created with totally different replacement levels (0, 25, 50, 7, and 100 by volume) of natural fine aggregate (NFA) with plastic fine aggregate (PFA). Compressive strength test, Split tensile strength test, Water absorption test, density, workability, and XRD analysis has been performed in this examination. Decreasing in compressive strength was just around 14% and diminishment in water absorption was around 37% for concrete containing 50% plastic.
