To enhance the antibacterial agent efficiency of antibacterial self-leveling material by compounding inorganic compound powder having the antibacterial property of specified specific gravity and specific average particle diameter.
Inorgnaic compound powder of specific gravity of 2.6 or lower and an average particle diameter of 20 μm or less is compounded in self leveling material. The specific gravities of cement and aggregate compounded in the self-leveling material, for example, are about 3.15 and about 2.6 respectively, the inorganic compound powder of lower specific gravity than these of cement and aggregate is more easy to float than the cement and the aggregate by bleeding after placing the self leveling material, as a result, it is easily concentrated in a surface layer part, and a contact area between the inorganic compound powder and a contaminant increases to improve action efficiency. In addition, when the average particle diameter of the inorganic compound powder is 20 μm or less and less than the average particle diameters of the cement and the aggregate, it is easy to float smoothly in the surface layer part of the self leveling material during bleeding. Thereby growth of bacteria and microorganisms which are apt to adhere the surface layer part is prevented and the surface layer part is made antibacterial.
