This document summarizes research on utilizing waste plastic in concrete. It begins by providing background on the large and growing problem of plastic waste. It then describes an study that created concrete with 10% waste plastic replacing cement, fine aggregate, or coarse aggregate. The concrete was tested on cubes and cylinders to determine compressive, tensile, and flexural strength at various ages. Results found the strengths decreased with higher plastic replacement but were still within acceptable limits for less important construction uses. In conclusion, utilizing waste plastic in concrete is beneficial for plastic waste management and increasing the durability of the concrete.
