<p>PURPOSE: To obtain antibacterial cement for preventing the inner and outer wall surfaces and the ceiling surface in a building and a facility constructed by concrete and mortar from being stained by bacteria or the like by uniformly dispersing and mixing an antibacterial component for sterilizing microorganisms of wide range such as bacteria, germs or yeast fungi in and with a cement material which is a base raw material of concrete or mortar. CONSTITUTION: An antibacterial cement is formed by adsorbing, on a dispersing agent consisting of fly ash, diatomaceous clay or diatomaceous earth, an antibacterial component constituted of 10-30wt.% of pyridine compound and 70-90wt.% of benzimidazol before dispersing and mixing the dispersing agent in and with a cement material at a such ratio that the substantial concentration of the antibacterial component is at least >=300ppm.</p> |
