This paper presents the findings of the study conducted to evaluate workability and compressive strength characteristics of rapid-setting concrete containing metakaolin. The experimental variable selected was the rate of cement replacement with metakaolin at 0, 5, 10, and 15 percent. The findings are summarized as follows: compared with the control specimens with no replacement rate, the workability and compressive strength of the concrete with 5% of cement replaced with metakaolin were comparable to those of control specimens at 4hours; however, at 72 hours, the compressive strength of the concrete with the same replacement rate was larger than the strength of the control specimens by 4.1%, while no increase in strength was observed at higher replacement rates, implying that the optimum replacement rate of cement with metakaolin is 5%.
