STEEL SLAG AS REPLACEMENT OF FINE AGGREGATE IN TERMS OF HIGH STRENGTH CONCRETE

The Steel slag, a result of steel making, is delivered amid the detachment of molten steel from polluting influences in steel making heaters. This can be utilized as sand in concrete. Steel slag sand by and large display a penchant to extend on account of the nearness of free lime and magnesium oxides that have not responded with the silicate structure and that can hydrate and grow in muggy conditions. This possibly far reaching nature (volume switches up to 10 percent or more owing to the hydration of calcium and magnesium oxides) could cause troubles with items containing steel slag, and is one motivation behind why steel slag aggregate are not utilized as a part of concrete development. The present research work deals with a view to develop efficient concrete by addition of steel slag to evaluate the effectiveness of the use of steel slag as a partial replacement in sand To replace Sand with various percentages 10, 20, 30, 40% of steel slag waste in M25, M30 & M35 concrete. Investigation have been carried out to study the effect of steel slag on various property of concrete like compressive, split tensile, flexural strength.
