ABRASION RESISTANCE OF CONCRETE AND THE USE OF

Abrasion resistance of concrete containing marginal

The abrasion resistance of concrete degrades considerably once the L.A. value of aggregates goes beyond 30%. Incorporation of pozzolanic admixtures in concrete mix improves the abrasion resistance of resulting concrete with maximum benefits being observed in case of silica fume. Important observations have also been made about the influence of

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.

Abrasion resistance is the ability of the surface of a concrete slab to resist wear caused by all kinds of abrasion mechanisms; such as vehicle wheels, foot traffic, scraping and impact. These mechanisms are complex and combinations of them, together with other influencing factors such as dust or water on the surface of the slab, cause wear to the concrete.
