Analysis of abrasion rates in concrete surfaces of hydraulic structures

Abstract

Abstract Abrasion of water-exposed surfaces in hydraulic structures can impose devastating defects in these surfaces leading to larger costs of rehabilitation and maintenance. One of the possible solutions is the improvement of concrete quality. Generally, several factors govern the abrasion resistance of hydraulic concrete. In the present study, previous experimental works, which carried out depending on the ASTM C 1138 test method, were collected, studied and analyzed precisely in order to estimate the effect of several factors that related with concrete quality on the abrasion rate of concrete. The results showed that the selection of cement type, inclusion of fibers, addition of silica fume and the election of the proper concrete type have the most effective influence among the remaining studied factors on the abrasion rate reduction.
