Experimental Study on Self-Compacting Concrete using E-plastic waste materials in partial replacement of coarse aggregate

Abstract

Use of waste materials and by-products is a partial solution to ecological and environmental problems. Utilization of these materials not only helps in getting them used in cement, concrete and other construction materials, it reducing the cost of concrete and cement manufacturing, but also has many indirect benefits such as reduction in land-fill cost, saving in energy, and protecting the environment from possible pollution effects. E-waste (EW) is abbreviation of Electronic waste, consists of discarded computers, TV, Laptop, refrigerators – basically all electrical or electronic appliance that has reached its end-of-life. Efforts have been made in the concrete area to use non-biodegradable components of E-waste (EW) as a partial replacement of the coarse aggregates.An experimental study is made by preparing specimens by utilizing E-plastic waste particles as coarse aggregates in Self-Compacting Concrete (SCC) with a percentage replacement from 0% to 30% i.e. (5%, 10%, 15%....up to 30%). And Conventional specimens are also prepared for M30 and M35 grade Self-Compacting Concrete (SCC) without using E-plastic waste aggregates. By conducting tests for both the specimens Fresh Properties and hardened properties of Self-Compacting Concrete (SCC) are studied. It is found that use of E- plastic waste aggregates results in the formation of Self-Compacting Concrete (SCC) which has lesser weight than that of conventional concrete. This study ensures that reusing of E-waste as coarse aggregate substitutes in concrete gives a good approach to reduce cost of materials and solve solid waste problems posed by E-plastic waste.
