Wear Law of Natural Pumice Concrete under Ice Friction

Abstract

Abstract: Ice wear is one of important factors affecting the damage of hydraulic concrete. In order to investigate the wear law of natural pumice concrete under ice friction, natural pumice in Inner Mongolia was used as coarse aggregate, and the effects of volume fraction of pumice aggregate, water-binder ratio and cementitious material hardness on the wear of natural pumice concrete were studied. The significance of different influencing factors on the wear amount of natural pumice concrete was analyzed. The apparent morphology of natural pumice concrete under ice wear was observed by super depth of field microscope. The results show that the wear amount of natural pumice concrete increases with the increase of pumice aggregate volume fraction and water-binder ratio, and decreases with the increase of cementitious material hardness. The volume fraction of pumice aggregate and water-binder ratio have significant effects on the wear amount of natural pumice concrete. The surface material of natural pumice concrete falls off under the action of cutting and fatigue wear mechanisms. The hole wall of the worn surface is damaged and the holes are enlarged.

Key words: ice wear, natural pumice concrete, wear amount, wear law, significance analysis, wear morphology
