MORTAR COMPOSITION

摘要

PURPOSE:To obtain a mortar composition capable of maintaining stable mildew resistance and antimicrobial properties for a long period of time by blending mortar with soluble glass powder containing silver ion or copper ion. CONSTITUTION:A mortar composition blended with soluble glass powder containing silver ion or copper ion. The soluble glass used is one which is controlled to have regulated dissolution rate and can elute silver ion or copper ion at a fixed rate for an arbitrary period by adding a silver compound or copper compound to the glass. Eluted silver ion or copper ion is adsorbed on cell wall of bacterial or microorganism or concentrated in the cell wall and prevents growth thereof by so-called OLIGOJINAMY effects and can develop fungicidal and antimicrobial effects. The soluble glass like this is made into powder of proper size and the amount of the soluble glass added to mortar is about 1-10wt.%.
