2824 EN 1338 abrasion resistance test, using 0-3mm sized rubber to replace sand in the concrete and reported a decreased abrasion resistance of CRC than normal concrete and it decreased with increasing rubber percentage. However, the use of ground granulated blast furnace slag was found to improve abrasion resistance.
The abrasion resistance properties of rubberized concrete were comparatively studied by taking silica fume and crumb tire rubber as the additives. The abrasion tests were conducted in accordance with the Chinese standard test method DL/T 5150 — 2001, two recommended test methods: under water method and ring method, were used.

Abrasion resistance is half that of natural rubber, and tensile strength ranges from 1,200 to 1,400 psi. However, these values are retained after extended immersion in oil. Basic properties of polysulfide polymers are determined by the type of chain structure and the number of sulfur atoms in the polysulfide groups.

With the increased abrasion resistance most properties stayed consist with the control, if not greater than, with the UHMW PE; the only drastic changes being the Durometer increase, slight Tensile decrease, and loss in Bashore rebound.
Rubber Abrasion Resistance 149 lack of correlation of abrasion resistance with other measures of strength. It should be noted that it is specific to soft, extensible materials, and thus it also accounts for marked differences in the nature of the wear process in rubbery materials compared to plastics and metals.
Nitrile is commonly used in applications requiring oil and solvent resistance, with a major market being the automotive industry, with major end uses including hoses, fuel lines, O-rings, gaskets and seals and the excellent abrasion resistant properties of the elastomer increase its suitability in these areas.
Even though NBS abrasion resistance, tensile strength and tensile modulus of TPU are much higher than those of EPDM and BR, TPU/EPDM (90/10) and TPU/BR (90/10) blends exhibit the higher NBS abrasion resistance, tensile strength and tensile modulus, than does of TPU.
Abrasion testing can be used to measure and predict overall durability of the material as it may perform in real world applications. Abrasion characteristics are critically important in many rubber and plastic applications as a measure of durability.

material rubbing against the rubber or thermoplastic cover. This is referred to as abrasion resistance where the belt covers tend to wear smoothly and evenly. The type of material conveyed also affects wear. For example, coal is relatively non-abrasive whereas, in comparison, hard rock and taconite pellets wear covers extremely fast.
A tough rubber part with high abrasion resistance will also be able to keep its form without being deformed or indented by hard physical objects. The snowplow blades are a great example of rubber abrasion resistant products. Ultimately, the tensile strength of rubber products affects their abrasion, tear, and impact resistance.
