11. A REVIEW ON EFFECT OF QUERY DUST AS A SAND REPLACEMENT IN PROPERTIES OF CONCRETE

Common river sand is expensive due to excessive cost of transportation from natural sources. Also, large -scale depletion of these sources creates environmental problems. As environmental, transportation and other constraints make the availability and use of river sand less attractive, a substitute or replacement product for concrete industry needs to be found. Concrete assumes the vital part and huge quantum of cement is being used in each development rehearses. Normal stream sand is one of the critical element of cement is becoming costly because of unnecessary expense of transportation from sources. Likewise huge scope consumption of sources makes natural problems.To beat these issues there is a need of practical other option and inventive materials. Quarry dust is a waste gotten during quarrying process it has as of late acquired great consideration regarding be utilized as a viable filler material rather than fine total. Additionally, the utilization of quarry dust as the fine total reductions the expense of substantial creation as far as the incomplete substitution for regular waterway sand. Configuration blend of M40 grade concrete with substitution of 25%, ,50%,100% of quarry dust. For Laboratory examination droop test ,compressive strength, split -rigidity and flexural strength of hardened concrete are carried out. In this paper, the properties of hardened concrete using quarry dust were investigated.
