APPLICATION OF INDUSTRIAL-WASTE MOLTEN SLAG TO REINFORCED CONCRETE BEAMS

Abstract

This paper describes the effect of industrial-waste molten slag on the mechanical behaviour of reinforced concrete beams in the slag replacement ratio of 0%, 40%, and 100%. Examination items are load carrying capacity, deflection, crack behaviour, and the bond characteristic of the reinforcing bar in reinforced concrete beam. The experimental results showed that, when slag replacement ratio is 40%, the influence of the slag on the bond-stress relationship of reinforcing bar and the crack behaviour in the reinforced concrete beam is small. Moreover, it was suggested that the possible replacement ratio of slag is dependent on the water cement ratio.
