Abrasion (also called “wear”) is wearing of the concrete surface by rubbing, rolling, sliding, cutting or impact forces. Abrasion (or wear) resistance is then the ability of a concrete surface to resist wear caused by rubbing, rolling, sliding, cutting and impact forces. Wear, which is the removal of surface material, is a process of displacement and detachment of particles or fragments from the surface. Abrasion mechanisms are complex and combinations of different actions can occur in many environments - for example, from truck tyres, foot traffic, scraping and impact.Abrasion testing is performed with BCA abrasion testing machine. The floor surface is tested by measuring the depth of wear created by three hardened wheels rotating over a circular area for a standard number of revolutions (2850+/-10).
