Recycling of E-plastic waste as a construction material in developing countries

This paper presents an experimental investigation on structural concrete with partial replacement of coarse aggregate using electronic plastic waste (E-plastic). In view of utilizing the non-degradable waste in the construction industry, the E-plastic from computer plastics was considered as coarse aggregate. Coarse aggregate was replaced with different percentages (10, 20, 30, 40 and 50 %) of E-plastic by volume. Tests were performed for properties of fresh and hardened concrete at different ages such as 7 and 28 days. From the investigation, it was noted that the workability of the mix was reduced against the increase in percentage of E-plastic. The compressive strength, split tensile strength, flexural strength of partially replaced concrete was comparatively less than that of the control concrete. The effect of adding the E-plastic in concrete reduced the dry density of the concrete and showed the high deformability behavior before failure. The lesser dry density may be having advantage in self-weight reduction in structural elements which leads to lesser attraction of pseudo inertia forces in the seismic prone area.
