Abstract The effect of using coal gasification slag as fine aggregate (CGS) generated from integrated coal gasification combined cycle for reinforced concrete beams was evaluated by bending, shearing, and axially-load tension tests. Results show that the long-term compressive strength increased with the use of CGS, but the crack initiation load tended to degrease. On the other hand, it was confirmed that the load-bearing performance was equivalent to that of concrete using a normal aggregate. Therefore, it is considered possible to use existing evaluation formulas to calculate flexural strength and shear strength. In conclusion, this study shows that CGS concrete can be used for structural members.
