Accelerated Abrasion Resistance Testing

Abrasion resistance is an important performance requirement in warehouse and industrial floors. Floors can be exposed to quite aggressive actions from trucks and other equipment.

Tests are carried out using our purpose designed and built equipment which conforms to the requirements of BS EN 13892-4: 2002. Known as the BCA abrasion test machine, the floor surface is assessed by measuring the depth of wear created by three hardened wheels rotating over a circular (template marked) area for a standard number of revolutions (2850 + / – 10).

The depth of wear is used to assess the quality of the floor and classifies it in accordance with BS 8204-2:2003+A2:2011. Each test is accompanied by a CoGri-GesPaP report. Where the classification is lower than required, Face can investigate and advise on the significance of the results, and on any remediation steps that should be taken.

Abrasion Testing, or any other topic related to floors can be provided as part of CoGri Expert Witness Services.

Table 3 – Classification of abrasion resistance and limiting depths of wear for the abrasion test: Recommendations for concrete bases, directly finished (DF) only, as wearing surfaces

Class Service Conditions Application Maximum test wear depth mm Typical examples (see 6.2)
Type of concrete Minimum compressive strength class a N/mm2 Minimum cement content kg/m3 Type of coarse aggregate Type of a1fine aggregatea1 Finishing process
AR0.5 (special)/DF Severe abrasion and impact from steel or hard plastics wheeled traffic or scoring by dragged metal objects Very heavy duty engineering workshops and very intensively used warehouses, etc. 0.05 Specially designed proprietary concretes   Special concretes which are not classified by strength class or minimum cement content and might contain aggregates that do not conform to 5.3. Special finishing techniques may be used. The suitability of concrete flooring for this class should be established with the manufacturer or flooring contractor offering warranty     
 AR1/DF Very high abrasion; steel or hard plastics wheeled traffic and impact Heavy duty industrial workshops, intensively used warehouses, etc. 0.1
 AR2/DF High abrasion; steel or hard plastics wheeled traffic  Medium duty industrial and commercial 0.2 Direct finished concrete C40/50 RC50 400 Aggregates conforming to 5.3.2 a1Fine aggregatea1 conforming to 5.3.3   Power floating and repeated power troweling as 10.7 
 AR4/DF Moderate abrasion: rubber-tyred traffic Light duty industrial and commercial 0.4 Direct finished concrete C32/40 RC40 325
* Concrete should conform to BS 8500-2.

Table 4 – Classification of abrasion resistance and limiting depths of wear for the abrasion test: Recommendations for concrete bases upgraded by dry shake/sprinkle finishes and for applied wearing screeds (WS)

Class Services Conditions Application Maximum test wear depth mm Type of wearing screed material Notes
AR0.5 (special)/WS Severe abrasion and impact from steel or hard plastics wheeled traffic or scoring by dragged metal objects Very heavy duty engineering workshops and very intensively used warehouses, etc. 0.05 Proprietary dry shake/sprinkle finishes on concrete grade at least as for AR3/DF Proprietary dry shake/sprinkle finishes, which are not classified by strength class or minimum cement content and might contain aggregates that do not conform to 5.3. Special finishing techniques may be used. The suitability of concrete flooring for this class should be established with the manufacturer or flooring contractor offering warranty.
AR1/WS Very high abrasion; steel or hard plastics wheeled traffic and impact Heavy duty industrial workshops, intensively used warehouses, etc. 0.1 Monolithic or bonded wearing screed

For wearing screed materials see 9.2.

Approved aggregates conforming to 5.3.4

a1Fine aggregatea1 conforming to 5.3.5.

Hand trowelling or power floating and repeated power trowelling as 10.7

 AR2/WS High abrasion; steel or hard plastics wheeled traffic Medium duty industrial and commercial 0.2
AR4/WS Moderate abrasion: rubber-tyred traffic Light duty industrial and commercial 0.4

Note: As well as the tables above, The Concrete Society’s Technical Report No 34 4th edition (Current) states that 1 test per 4000m2 is adequate, and that the minimum required abrasion resistance should be 0.20mm. This equates to a minimum requirement of AR2.

It is also worth noting that prior to TR34 4th Edition quoted above, no official document has ever given any guidance on a sampling rate.

A floor’s ability to resist abrasion is a very important factor. To carry out an abrasion test, eight test locations are marked on the floor using a machined template. Readings are then taken at each of the eight test locations using a digital depth gauge.
