Adhesion of Suspended Particles on Concrete Surface

Abstract

Soiling on the exposed concrete surface is serious problem from the view point of marring the appearance of concrete structures and the landscape. In order to obtain a basic knowledge about the soiling on exposed concrete surface, the effect of mortar surface properties on the adhesion of suspended particles on mortar surface was studied. The mortar surface which the coefficient of water penetration is high or which the coefficient of adhesive roughness is high has a tendency that the amount of particles adhesing on the mortar surface is high.
