Abstract: 

Abrasion damage in concrete slabs on the ground and hydraulic structures, which are widely used in the world, is a serious problem and may stop their serviceability. Nowadays, strength is not considered the only important factor in concrete properties, because of financial and engineering points of view; the durability of concrete in different conditions is prominent. In this study several mixtures of concrete with ordinary and granite aggregates, silica fume, S.B.R polymer and different WIC ratios were tested to evaluate abrasion resistance of concrete subjected to wearing caused by heavy traffics. The selected test was ASTM C779-a, test method for abrasion resistance of horizontal concrete surfaces. Also an rxperimental model for evaluating the abrasion resistance of concrete was suggested. The results show that the incorporation of silica fume, S.B.R polymer and also granite aggregates in concrete improve its abrasion resistance. The suggested mathematical method can predict abrasion resistance of concrete by determining the abrasion depth.
