Paper Title
Concrete Mixture With Plastic As Fine Aggregate Replacement

Abstract
Abstract- The objective of this research is to investigate the effectiveness of using waste plastic as fine aggregate replacement in concrete mixtures. The compressive and tensile strengths of various concrete specimens were tested to determine how the incorporation of recycled plastic as a replacement fine aggregate would affect the development of strength in the mixes. Six mixes were compared at replacement increments of 0%, 10%, 20%, 30%, 50% and 100%. All stages of plastic replacement showed a noticeable decrease in compressive strength. The 10% replacement level only showed a 15% loss of compressive strength at 28 days compared to the control. Despite being much weaker in compression, the tensile strength test showed that the 10%, 20% and 30% replacement increments were stronger in tension compared to the control. An additional test was conducted to determine whether the plastic aggregate would change the heat absorption and heat transfer of the concrete. This test showed noticeable difference between the test samples and the control. The 10%, 20% and 30% replacement mixes showed a significant decrease in heat absorption, and a minor decrease in heat transfer through the test slab. Index Terms- alternative recycling methods, green concrete, plastic, sustainable building materials.
