COMPRESSIVE STRENGTH EVALUATION OF ECO-FRIENDLY CONCRETE REPLACING SAND PARTIALLY WITH HIGH IMPACT POLYSTYRENE

This paper presents the variation of compressive strength with an increase in percentage fine aggregate replacement with High impact polystyrene at the age of 7, 14 and 28 days curing periods. It helps in finding optimal percentage replacement of electronic waste HIPS (High Impact Polystyrene) as sand in concrete. Thus possibility of reduction in plastic disposal problem can be achieved. Thereby energy consumption and protects environment from pollution. Investigation reported that reduction in compressive strength up to 20% is minimal and reduction raises as percentage of HIPS replacement increased further. The results obtained as compressive strength reduced when compared to conventional concrete, however achieved target mean strength of the mix design. As an alternative to sand scarcity problem as well as to reduce e-waste disposal problem, this eco-friendly concrete belongs to medium weight serves its application for nonstructural elements.
