Abstract :

Environmental concerns due to the over-exploitation of sand have led to restrictions on extraction of sand across India. Thus, the construction industry has huge demand for a suitable environmentally friendly alternative to sand. On the other hand, recycling of waste plastic is rarely done in India, with nearly 40% left in landfill. The dumping of these plastic materials, which degrade at extremely low rates, will lead to high negative impacts in the society. These plastic wastes will persist in the environment for very longer period, which is a long-term environmental concern. In order to solve both these problems, processing the waste and using it as a partial replacement of sand can be done. As there is strength degradation observed in various previous studies of plastic incorporation in concrete, Rise Husk Ash (RHA) and Silica Fume (SF) are replaced for cement to enhance the strength. Keeping the RHA and SF proportion to be constant, the maximum amount of plastic waste that can be replaced for sand is found out. This paper mainly focuses on the mechanical behaviour of the plastic impregnated concrete. The result concludes that the maximum amount of plastic that can be partially replaced for sand in concrete is 30%. Beyond that, the concrete will not satisfy the minimum requirements of the codal provisions.
