The waste utilization is sustainable solution to the environmental problem and use of waste materials reduces the cost of concrete in the production of house building environment. The replacement percentages of recycled concrete aggregate(RCA) were 0%, 5% & 7% respectively. The partial replacement of RCA to achieve the mechanical properties (compressive strength) and chemical properties (corrosion resistance and alkali attack) of concrete by utilizing E–waste as compared with the ordinary conventional concrete. Key Words: Electric and Electronic euipment’s (WEEES), Recycled Concrete Aggregate(RCA), Compressive strength, Workability. 1. INTRODUCTION Concrete is that the most generally used man-made construction material. It’s obtained by mixing cement, water, aggregates and admixtures (if needed), in required proportions. The mixture when placed in forms and allowed to cure, hardens into rock – mass referred to as concrete. The strength, durability and other characteristics of concrete depends upon the properties of its ingredients, on the proportions of mix, the tactic of compaction and other controls during placing, compacting and curing. The fat growth in technological world has resulted in tons and plenty of by-product or waste materials or Electronic waste, which may be used as a ingredient in concrete. the utilization of those by-products not only helps to utilize these waste materials but also enhances the properties of concrete in fresh and hardened states. Perhaps the foremost successful Supply Chain Management (SCM) is E-Wast because it improves both strength and sturdiness of concrete to such we can extent that modern design rules involve addition of E-waste materials in concrete brick for design of high strength concrete. 1.1 OBJECTIVE The objective of the present research work is to find out the different properties of Electronic waste. To reduce the utilization of Coarse aggregate by partial replacement of E-Waste. To enhance the best environmental alternate for cement. 1.2 MATERIAL AND METHODOLOGY 1.2.1 CEMENT Ordinary Portland Cement (53 grade) conforming to IS: 12269 -1987 and with the specific gravity 3.23 was used for casting all the specimens. Tests conducted on cement are fineness of cement by sieve analysis (using 90 µ sieve), specific gravity using Le-chatlier’s apparatus, initial setting time and final setting time using vicat apparatus. Table-1 properties of cement Sl.No TESTS RESULTS 1 Specific Gravity 3.23 2 Initial Setting Time 37 3 Final Setting Time 535 4 Consistency test 29.5 5 Fineness test 4.93 1.2.2 E-Waste Silica fume is a byproduct of producing silicon metal or ferrosilicon alloys. One of the most beneficial uses for silica fume is in concrete. Cement is partially
