Abstract
In this study, performance evaluation of recycled coarse aggregate and steel fiber reinforced concrete was carried out in an effort to reduce the environmental load. A 30% of natural coarse aggregate was replaced with recycled coarse aggregate, and the volume fraction of steel fiber was used as a variable. As a result of evaluating the material strength and flexural strength, the strengthening effect of steel fiber was confirmed. In order to evaluate the applicability of recycled coarse aggregate, it was evaluated that there was no difference in the strength from the comparison using the natural coarse aggregate of the same condition. Also, the proposed formula considering the steel fiber strengthening factor was evaluated to be able to predict the flexural strength of SFRC beams.
