The fluidity and compressive strength of mortar using five types of slag fine aggregate for concrete, including coal gasification slag aggregate, were investigated. As a result, the following conclusions were obtained. Even if the particle size distribution of the fine aggregate was made the same, the effect of the fine aggregate volume fraction on the J14 funnel flow test results differed due to differences in the particle shape of the fine aggregate. Furthermore, in this experiment, the change in the compressive strength of the mortar due to adjusting the particle size distribution of the fine aggregate was not large.
