Waste materials have been used to produce sustainable light weight concrete. Due to rapid industrialization, disposal of large amount of waste material such as fly ash,silica fume,recycled plastic and EPS cause environmental issues due to pollution.Other materials like coconut shells, Expended PolyStyrene beads(EPS),pumice stone,recycled plastic, periwinkle shells,waste glass particle, sawdust ,thermocol ,egg shell powder,fly ash, silica fume,clay etc have also been used to make Structural Light Weight Concrete. Considering the factors such as being eco-friendly, sustainable and considerably reducing the cost and weight of concrete various waste materials are used in concrete . Coarse aggregate,fine aggregate or cement has been partially replaced by these waste materials to produce structural light weight and low cost concrete. Coarse aggregate has been partially replaced by waste materials such as coconut shells, Expended PolyStyrene beads(EPS),pumice stone,recycled plastic, periwinkle shells etc. Fine aggregate has been partially replaced by waste materials such as waste glass particle, sawdust ,thermocol ,egg shell powder etc. Cement has been partially replaced by fly ash, silica fume,clay,egg shell powder respectively. All the materials mentioned above can be used in concrete as an alternate material to reduce both weight and cost of concrete. From experiments it has been observed that when the materials mentioned above are used in concrete as partial replacement of basic ingredients compressive strength and split tensile strength decreases with increasing percentage of these materials but optimum percentage of these materials gives better strength as same as conventional concrete. Use of above materials in concrete increase strength or reduce cost or both . Thus the problems related to environmental issues caused by above materials can be reduced and there by produce structural light weight concrete in a constructive manner by replacing them in concrete.
