Properties of Concrete Coarse Aggregate Partially Replaced With Coal Washrey Rejects

D. Tharun Kumar, R. Rajesh Kumar


Abstract: The interest of normal aggregates is quickly turning out to be high step by step in the development industry. Different endeavors are being made to discover substitutes for normal aggregates. In India, around 70 % of power is created by burning of good quality coal. During the time spent coal washing, substantial amounts of sullied coal are being rejected and bringing on transfer issues. These rejected sullied coals are called as Coal Washery Rejects (CWR). To keep up the ecological manageability, an endeavor has been made in the present study to utilize new material CWR as fractional substitution of coarse aggregate in concrete. The compressive strength of concrete containing CWR at various substitution levels (0 % - 30 %). The compressive strength qualities were compared with M 25 evaluation of conventional concrete (CC). From the outcomes, it is watched that the expansion in CWR substitution level diminished the compressive strength. This decrease was marginal at 20 % and 30 % substitution levels, however beyond 30 %, the reduction was especially huge. Henceforth, it is uncovered that 30 % CWR substitution can be considered as ideal level in the development business. From the compression strength results durable property Rapid chloride permeability test (RCPT), tests were conducted at the replacement level of 30 % only.
