A brief review on polyvinyl chloride plastic as aggregate for construction materials
Summary
Researchers reviewed three decades of studies on using recycled PVC plastic waste as an aggregate in concrete and cement, examining how particle size, surface treatment, and mixing ratio affect the strength and durability of the resulting material. The review identifies practical strategies for incorporating PVC waste into construction, reducing plastic pollution while supporting sustainable building.
Abstract Recycling plastic waste in construction applications is a common concept for innovative concrete development. Enormous studies have been conducted for the past three decades. Yet, there is a need in understanding the behavior of the plastic, its effects on cement composite, and the possible approaches for extending the usage of plastic waste to be an alternative resource component of cement composites. For the first section, the types of plastic and its characteristic as well as the overview on the plastic production and waste generated are discussed briefly. Further, the paper is focused on the relevant information on the plastic waste in cement composites and the polyvinyl chloride (PVC) plastic as plastic aggregate in cement composites. The review also includes the factors that influence PVC aggregate on cement composites which are physical characteristics of PVC plastic aggregate, the effect on mechanical and permeation properties of cement composites. The paper also examines the possible approaches in improving the PVC plastic aggregate characteristics, which can enhance the usage of PVC plastic aggregate for sustainable construction material.
