Abstract
The consumption of various forms of plastic has been increased in recent days due to theboost in industrialization and other human activities. Most of the plastic wastes areabandoned and require large landfill area for storage. More importantly, the lowbiodegradability of plastic poses a serious threat to environment protection issue. Variousmethods have been followed for the disposal of plastic in an attempt to reduce the negativeimpact of the plastic on the environment. Recently, various types of plastic have beenincorporated in concrete to minimize the exposure of plastic to the environment. The aimof this study is to investigate the properties of concrete containing polyethyleneterephthalate (PET), and high density polyethylene (HDPE) plastic that were used aspartial replacement of coarse aggregate (CA). In this study, four compositions of stoneaggregate(S): plastic waste ratios have been used by volume basis: 100% S: 0% Plastic(control concrete), 90% S: 10% PET, 90% S: 10% HDPE, and 90% S: 5% PET+5%HDPE. The effects of waste plastic addition on the mechanical properties of concrete arepresented in this paper. Test results reveal that minimum reduction in compressivestrength has been found 35% in case of 10% PET plastic replaced concrete whereassplitting tensile strength for 10% PET replaced concrete has been increased by 21% whilecompared to control concrete. In addition, fresh unit weight of concrete containing plasticwaste has been decreased by 4% in comparison to control concrete. <br> <em>(4) (PDF) Experimental investigation on the properties of concrete containing post-consumer plastic waste as coarse aggregate replacement</em>.
