Review of Abrasion Mechanisms and Influential Variables on The Disintegration Resistance of Concrete

Abstract

Abstract In many hydraulic constructions such as dams, spillways and stilling basins, large of amounts concrete can be damaged depending upon the long-term activity of water-borne solids. To a great extent, for hydraulic structures, the durability relies upon the resistance that the concrete surface offers to mechanical wear. The surface damage caused by the uninterrupted material removal process, induced by the impact of the water borne solid particles, is termed hydro-abrasion. In nearly all hydraulic structures, this kind of progressive deterioration of the concrete surfaces is observed, to different intensities. Obviously, such hydro-abrasive concrete wearing normally results in a reduction in the service life of the hydro-technical facility, and consequently because of the repairs necessitated, the non-functioning of the facility during the repair period results in an expenditure spike. The objective of this article is to: understand the mechanisms of concrete abrasion-erosion followed by brief iscussion about the factors remarkably impact the rate of abrasion erosion also through these studies, it was concluded the improvement of the abrasion resistance needstomodify the concrete characteristics also increase the compressive strength.
