The Performance of Lightweight Concrete with Recycled Polyethylene Terephthalate and Polypropylene as Demising Wall

Abstract The use of concrete has always been an important construction material used throughout the industry in world. objective this study is to explore potential using lightweight block mixing with plastic waste and additional as a sustainable for constructing demising wall current industry. research conducted quantitatively through experiments test density strength materials. A series are based on two types plastics which Polyethylene Terephthalate (PET) replacement coarse aggregate Polypropylene (PP) fibres corresponds percentage cement mass added into mix each different observe variations tests. findings show that 0.5 % showed outstanding results compressive compared control specimen PET specimen. However, if comparing amount recycled incorporated same size block, higher recycling rate 27 times PP fibres. From findings, will contribute wider range building materials choices designer or architect project.
