Sustainable Waste Management Of Polyethylene Terephthalate (Pet) And Rubber Crumb In Concrete

Abstract
Several recent studies have been conducted to investigate the possibility of waste materials in construction building especially Polyethylene Terephthalate (PET) and rubber crumb. From the studies, there is a wide range of possible civil engineering applications for these waste materials. In this context, this research was conducted to provide more data on the combination of both waste materials to be used as partial replacement in concrete. The performances of the concretes were assessed through its compressive strength, water absorption and skid resistance. The fine aggregate was replaced by PET and rubber crumb at 10%, 20% and 30% by weight of binder and tested for 7, 28, 60 and 90 days of curing. The results showed that by increasing the replacement of PET in higher proportion (up to 20%) and rubber crumb (up to 10%) the compressive strength of concretes decreasing. While, the water absorption of concretes increased with the increased of PET and rubber crumb replacement. For skid resistance, RC concrete were higher compared to control, rubberized-PET and PET concretes. The main findings of this investigation revealed that these waste materials could be used successfully as partial replacement for fine aggregates in concrete production.
