Experimental Study on Effect of Plastic Waste as Coarse Aggregate on Concrete Properties 1 Global Journal of Science Frontier Research Volume XXI Issue VI Year 2021 5 ( H ) © 2021 Global Journals Version I increases, so does the workability. This can be attributed to the smooth surface and low absorption characteristics of Plastic aggregate. iii. The higher the percentage replacement of the coarse aggregate with recycled PET plastic aggregate, the lesser the compressive and flexural strength. Concrete mix with addition of plastic PET aggregate has lower water absorption property compare to the control concrete, and which is a function of the proportion of the plastic PET aggregate in the matrix. iv. It is recommended that PET concrete should not be used as reinforced concrete due to the fact that the values gotten at 28days for 10%, 20% and 30% of PET aggregate replacement were lower than the strength recommended by standards. However, it can be used where light weight concrete coupled with water proof or resistance is required.
