PROBLEM TO BE SOLVED: To provide a self-leveling composition for cement which has strong acid-resistant, excels in workability during application, is capable of reducing occurrence of shrinkage and crack after application and obtains highly accurate surface smoothness. SOLUTION: The self-leveling composition comprises alumina cement and aggregate, in which a weight ratio of alumina cement to aggregate is in the range from 30 to 70 to 60 to 40, further an anti-foam agent, a thickener and a dispersing agent. |
