Experimental Study of Concrete By Partial Replacement of Coarse Aggregate By E-Waste

The most widely used material in the world is concrete, consequently there is a large requirement for raw material of concrete such as Fine Aggregate, Coarse Aggregate and cement. the huge extraction of the aggregate for manufacturing of concrete as serious effect on the environment due to depletion of natural resources and pollution. This affects the eco system to great extent. Hence the project deals with finding replacement for the existing raw material used in concrete by replacing the fine aggregate from river which is largely used in construction by chiton shell. Sea shell is the corpus of the marine organism. The sea shell has been grinded to 4.75mm and then replaced in the concrete. M20 mix was used and cubic specimen were casted for 5 different percentage of partial replacement as 0%, 5%, 10 %, 20%, and 25 %. All the specimens are tested for 7 & 28 days compressive, flexural and split tensile strength. it has been noted that the highest strength is obtained for 25% replacement of chiton shell. it was also observed that addition of sea shell power in concrete reduced workability hence superplasticizer were added to improve the consistency.

Concrete is the most important engineering material and the addition of some other material may changes the properties of concrete. This research is carried out to produce a low cost and eco-friendly concrete steel blocks. Studies have been carried out to investigate the possibility of utilization a broad range of material of partial replacement of coarse aggregate. Here the partial replacement of coarse aggregate by expanded polystyrene in the percentage of 25%, 30%, 35%. The tests were carried out on standard cube of 150x150x150mm for 7, 14, 28 days to determine the optimum percentage replacement. The steel blocks are made in dovetail shape and EPC is poured in it. The strength of steel composite blocks are then studied. The aim of the research is to know the behavior of steel composite blocks after addition of EPS and find its application.
