AN EXPERIMENT INVESTIGATION ON CONCRETE BY USING E-WASTE AS FINE AGGREGATE AND ENHANCED THE THERMAL INSULATION AND ULTRASONIC PROPERTIES

This study focuses on the performance of M30 concrete prepared with E-plastic waste (PCB cutting waste) as part of the fine aggregate to find the thermal and ultrasonic properties. A detailed experimental study had been carried out to analyze the thermal and ultrasonic properties of conventional concrete by casting the cube specimen. The compressive strength test was conducted using casting slab panels of 1'x1' with various thicknesses like 2”, 4”, 6”, 8” and different temperatures in a closed chamber. The heat transformation and U-factor were calculated and the insulation properties of the E-waste concrete are compared with the conventional concrete. A replacement of cement with fly ash (10% by weight) can be used effectively in concrete.
