Abstract

Introduction: Malaysians on average produced approximately 19,000 tonnes of solid waste annually with 592.8 tonnes of it is polyethylene terephthalate (PET) plastics. One of the ways to reduce plastic wastes is to made it as one of the components in geopolymer bricks. Objectives: This paper presents a review on the comparison between properties of geopolymer bricks and conventional Ordinary Portland Cement (OPC) bricks and comparison of properties geopolymer bricks with different concentration of PET plastics. Methodology: For this review paper, 45 out of 2,013 papers have been chosen to be reviewed. The search engine used mainly by Google Scholar and the keywords used to choose the papers are “Geopolymer bricks with polyethylene terephthalate”, “Ordinary cements bricks vs geopolymer bricks” and “carbon dioxide emission from geopolymer bricks with PET”. Results and Discussion: Geopolymer bricks have higher compressive strength and lower water absorption rate compared to conventional OPC bricks. There is no significant difference between both type of bricks in terms of efflorescence as both type of bricks gives the same results. The compressive strength of geopolymer bricks can be increase or decrease aligned with PET concentration. The water absorption rate of geopolymer bricks is directly proportional to the PET concentration. There is no significant difference between geopolymer bricks with different PET concentration in terms of efflorescence as all of the studies shows equal results between the bricks. The utilization of PET in geopolymer bricks can be considered as acceptable as most of the studies approved the use of PET as it satisfied the minimum requirement of bricks. Conclusion: The use of geopolymer bricks with PET has not been commercialized due to several reasons. The possible reasons are related to the methods for producing geopolymer bricks, the cost of certain constituents used in the making of geopolymer bricks, the potential contamination from the waste materials used, the absence of relevant standards, and the slow acceptance of geopolymer bricks by industry and public. Keywords: Geopolymer bricks, Compressive strength, Water absorption, Efflorescence, Carbon dioxide emission
