Use of Non-Chloride Accelerator with E-Waste as Partial Replacement of Coarse Aggregate in Concrete

In present scenario, there is a huge demand of making concrete which gain their full strength prior to the maturity period, so that the concrete structure can be made available for use in a time less than as compared to the normal concrete structure. In addition to this the use of waste material in concrete is one of the most attractive options to make it economical and environmental friendly. Research work conducted on the concrete made using triethanolamine (TEA) as an accelerator to achieve early strength of concrete, with the partial replacement of coarse aggregate in different percentage by electronic plastic waste to make concrete eco-friendly with low cost is being presented in this paper. Concrete mixture M25 is designed as per the guidelines of IS 10262:2009; Forty eight cubes are casted and tested for compressive strength after curing period of 3, 7, 14 and 28 days. The best results are obtained with 0.25 % triethanolamine (by weight of cement) and 4 % E-waste as a replacement of coarse aggregate and it can be concluded that up to replacement of 6 % of coarse aggregate the E-waste can be used effectively with triethanolamine.
