To Study the Effect of Steel Slag and Dismantle Aggregate on the Behaviour of Concrete

Natural aggregates are becoming increasingly scare and their production and shipment is becoming more difficult. steel slag is an industrial by product obtained from the steel manufacturing industry. Steel slag can be used in the construction industry as aggregates in concrete by replacing fine aggregates and dismantle aggregates can be used by replacing coarse aggregate. Steel slag is currently used as aggregate in hot mix asphalt surface applications, but there is a need for some additional work to determine the feasibility of utilizing this industrial by product more wisely as a replacement for both fine and coarse aggregates in a conventional concrete mixture. Partial replacement of natural aggregates with steel slag and dismantle aggregate may lead to environmental benefits. The primary objective of the present study was to evaluate the strength properties (compressive and split tensile strength) with steel slag as partial replacement for fine aggregate and dismantle aggregate for coarse aggregate.
