Abstract: The goal for taking p this exploration is because of the at that now a days the natural sand affirming to Indian standards is becoming scarcer and costlier because of non-accessibility in time for the reason that law of land, unlawful digging by sand mafia etc… For this reason a motivation has been done to identify a new source of aggregates. The objective of this study is to verify the appropriateness, feasibility &forthcoming utilization of Stone powder for future years. Stone powder is a loss from the quarry preparing units. It accounts 30% of the residue from the quarry industry. Use of stone powder as a replacement of Natural sand reduces cost of construction but also it helps to reduce the wastage of material so it can be give a good impact to the environment. Hence in the current study an attempt has been made on concrete mix of grade M40 by experimenting the strength properties & durability of concrete by replacing Stone powder by 25%, 50%, 75% & 100% to Natural sand and expand the project the addition of steel fibers of 0.5%,0.75% and 1% have done and also the effect of curing of 3% of H2SO4, HCI and Sea water on these concrete mixes are determined by immersing these cubes for 28 days, 90 days in above solutions and respective changes in compressive strength, tensile strength & weight reduction observed and it has been found that the compressive, split tensile strength of concrete made of stone powder increases nearly 17% and 60% with addition of steel fibers. The durability studies show a decrease of nearly 17% in compressive strength.
Key words: Stone Powder (SP), Strength & Durability, Steel Fibers
