The surface of concrete tiles is weak in moisture that it occurrence efflorescence, but in the former study we found that it is possible to ensure moisture stability of concrete surface by autoclaving. So this study is to discuss the moisture stability and physical properties of high-strength flossy concrete according to time and temperature of autoclave curing. As the results, by increasing time and temperature of autoclave curing, compressive strength and surface hardness increased and glossiness decreased. In the case to 3 hour and 180℃ of autoclave curing, there is not efflorescences in moisture stability test.
