About this site

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.

Abrasion-Erosion Resistance of Fiber-Reinforced Concrete

Thirteen concrete mixtures of three watercement ratios ranging from 0.40 to 0.72, each containing one of four different types of steel fibers, were tested. As is true of concrete without steel fibers, the abrasion-erosion resistance of FRC increased with a decrease in water-cement ratio and consequent increase in compressive strength.
