EXPERIMENTAL EVALUATION OF POLYMER LATEX EFFECT ON DURABILITY OF CONCRETE RECYCLED WITH PLASTIC WASTE

Abstract

In this study, we examined the effect of applying the waste plastics made of high-density polyethylene and polymer latex simultaneously on the physical properties and durability of concrete. For this purpose, high-density polyethylene has been substituted by sand in the amount of 10, 20, 30, and 40% volume. One percent of polymer latex has been substituted by cement. This study aimed to answer one question: “What are the effects of polymer latex on the durability of concrete containing high-density polyethylene plastic aggregates? According to the results, increased plastic wastes made of high-density polyethylene in addition to polymer latex leads to increased consistency, decreased density, increased percentage of air content, increased water absorption as well as the permeability of chloride ions. The samples lack of plastic wastes containing 1% of polymer latex in comparison to the reference sample showed 7% more slump and 17% more air in fresh concrete, 25% more chloride permeability, and 60% more water absorption. Also, the sample containing 40% waste plastic in addition to 1% polymer latex showed 33% more slump, 9% less density, 275% more air content, 133% more chloride ion permeability, and 240% more water absorption compared to the reference sample.
