Development of structural concrete with the help of plastic

waste as partial replacement for sand



Polyvinyl chloride (PVC) bags, polyethylene terephthalate (PET) bottles, injection moulded plastics and many other plastic products have a wide range of applications in all fields of engineering. Worldwide usage of plastics is growing, creating large quantities of non-biodegradable and environmentally damaging waste.

The proposal looks to utilise these waste plastics as a replacement for up to 10% of the sand in concrete, with a small effect on compressive strengths. This has the dual benefits of using a waste product in a new way while reducing the damaging mining of sand from riverbeds (the indiscriminate mining of which is banned in most states). This proposal could provide the booming Goan construction industry with much needed alternatives to sand. In addition, studies on workability, durability and crack control will be undertaken by considering the utilisation of chemical admixtures as well as plastics. The concrete thus obtained will be utilised throughout the built environment and future research could develop new areas of application.
