Using recycled PET waste bottle as clasp of ring strips in hollow concrete blocks in Iraq

الملخص

Solid waste is becoming a worldwide issue that must be delt with to alleviate resource depletion and to face the pollution problem. One of the major components in solid wastes is plastic. The yearly waste generation of plastics has been rising significantly. With high health problem associated with plastic waste, many approached were introduced for recycling. Using plastic waste in concrete mix is one approach for plastic recycling that is gaining more interest globally. In Iraq, where huge amounts of plastic waste are generating daily, the need for this approach is vital. Hollow concrete blocks are of the most public building bricks used around the country. This paper aims to examine how properties of compressive strength, flexural strength, water absorption, and dry density would affect when hollow concrete blocks are used for recycling plastic waste processed as clasps of ring strips. After cutting and arranged, PET ring clasps were introduced to the mix in varying quantities (3, 4, 6, and 8) and added to hollow blocks of size 360 mm x 200 mm x 200 mm. After concrete blocks casting and curing for 28 days, they were tested for their physical properties. Most of the central physical properties of these hollow blocks were identified and showed in this study. The results revealed that 6 ring clasps strips of PET (2.4 kg plastic/cubic meter of concrete) added was the optimum mix.
