Abstract

Single use plastics are plastic that only can be used once before being recycled or thrown away. The single plastic used has become a main problem for disposal. The aim of this study is to develop an eco-friendly construction bricks that incorporate single use plastic polyethylene terephthalate (PET) plastics as a solution to reduce the disposal issue. The bricks were prepared by using cement and sand with proportion of 4%, 8% and 12% of PET. The bricks were assessed for it compressive strength, water absorption and white precipitation. Carbon footprint was calculated for all the bricks. The results indicate that has highest compressive strength was conventional bricks (12.4 N/mm2) followed by bricks that contain 5% of plastic (11.6 N/mm2), 10% (5.96 N/mm2) and 15% (2.98 N/mm2). This is because plastic cannot bind well with other mixture in the bricks. Next, more water is absorbed with the increased of PET. Bricks with less plastic contain (4%) have the lowest percentage of water absorption which is 21.88% as compared 8% (25.14%) and 12% plastic (29.82%). Plastic does not intact well with the other mixture. The efflorescence test showed a positive result as all the bricks with PET does not have any white precipitation on the surface. Presence of white precipitation on the bricks would leads to serious problem because it can cause dry rot of woodwork, disintegration of masonry, decay and crumbling of plaster. The carbon footprint for the bricks reduced with the increased of PET. The result of compression strength, water absorption, efflorescence and carbon footprint was discussed and reviewed. It can be concluded that the compression strength are reduced and percentage water absorbed are increase, due to the incorporation of plastic waste into the brick mixture. However, efflorescence and carbon footprint showed a positive result. Keyword: Polyethylene Terephthalate (PET), brick, Compressive strength, Water absorption test and Efflorescence test
