Abrasion Resistance


Abrasion Resistance - The ability of the floor surface to withstand the abrasion produced by long term use of the floor.

Technical Information

Abrasion Resistance
Abrasion Resistance

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 and well-cured floor using concrete strength class C35/40. Lower concrete strength classes may require a dry-shake topping to achieve adequate abrasion resistance.
Abrasion Resistance Test
Abrasion Resistance Results Following a Test

A test to measure the abrasion resistance of a floor surface is described in EN 13892-4. The minimum age of test is not noted but the concrete must have developed its required strength, i.e. a minimum of 28 days is considered sensible. It is suggested that a sampling rate of 1 test per 2000m2 (3 minimum) is adequate. The maximum limit of abrasion should be 0.20mm.

If a floor is to be tested, it should be noted that the resin-based curing compounds create a layer or "skin" on the surface that can be impenetrable to the abrasion test machine.

Inadequate abrasion resistance in service can be improved by surface-penetraiting resin sealers.
