Improving the abrasion resistance of concrete

A. Actions needed to resist abrasion depend on the type of structure and abrasive action to be resisted. For concrete floors, the mortar fraction needs to be resistant to abrasion (ACI 302.1R). Abrasion resistance of concrete is measured by different standard test procedures: ASTM C418, ASTM C779, ASTM C944, and ASTM C1138.
