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. Excessive and early wear can be caused by the use of under-specified or non-compliant concrete or water damage at the construction stage.
In normal warehouse working conditions, poor abrasion resistance is rarely a problem for a typical power-trowelled
floor using concrete strength class C35/40. Lower concrete strength classes may require a dry-shake topping
to achieve adequate abrasion resistance.
