A STUDY ON EFFECT OF E-WASTE AS PARTIAL REPLACEMENT FOR COARSEAGGREGATE ON FRESH AND HARDENED PROPERTIES OF CONCRETE.

Abstract

  The experimental study deals with assessing the potential of electronic waste or E- waste as partial replacement for coarse aggregate in concrete. The coarse aggregate partially replaced with 10%, 12% and 15% of E-waste by weight. The physical properties of electronic-waste were assessed and compared with coarse aggregate. The fresh and hardened properties of conventional concrete and E-waste blended concrete were performed. The results concluded that the fresh properties such as slump and compaction factor of E-waste based concrete decreased with increase in percentage of replacement of e waste as compared to conventional concrete. The hardened properties such as compressive Strength and split tensile strength were also decreased for with increase in percentage of replacement of E- waste by weight of coarse aggregate as compared to conventional concrete but 12% of E-waste replacement shown comparable result with conventional concrete. Thus, we can conclude that 12% is the optimum percentage of E-waste replacement by weight of coarse aggregate in concrete.
