Several factors influence the abrasive qualities of a concrete surface. Mix design, exposure conditions, placement and finishing regimens are foremost. For instance a broom finish offers more skid resistance however it will demonstrate wear much quicker than a steel troweled finish will.
Whatever these conditions are should be tested if the abrasion qualities are a real concern. ASTM C-672 Scaling resistance and ASTM C-31 Compressive Strength are the two test that are all telling as to what you can expect.
Can be very important! Concrete Dusting is a problem in areas where electronics attract silica dust from abraded concrete surfaces, causing problems with the electronics. Use of a product called "StableCrete" is a way to stop dusting and improve compressive strength of a concrete.
This material penetrates into a concrete and forms a solid inside the capillary system of concrete making it more dense. It also waterproofs and gives acid resistance to the concrete.
Abrasion resistance is low.
The durability of concrete is its ability to resist weathering action, chemical attack, abrasion, or any process of deterioration. The strength of concrete is the ability of the concrete to withstand pressure or force.

Defined as 'a relative measure for evaluating the resistance of iron ores to size degradation by impact and abrasion' (ISO 3271:1995), also known as abrasion index. Index used in certificate of analysis of iron ore pellets.
abrasion resistance is the resistance in abrasion

Abrasion, Resistance
The ability to withstand scratching and abrasion is called abrasion resistance. It measures a material's ability to resist surface damage when rubbed against another material. Materials with high abrasion resistance are more durable and long-lasting.
The unit of abrasion resistance is typically measured in terms of cycles, such as the number of cycles until the material shows signs of wear or damage. Another common unit is the Martindale test, which measures abrasion resistance in terms of the number of rubs before wear is visible.
Abrasion resistance is low.
ASTM D 123 describes as followsAbrasion, n---the wearing away of any part of a material by rubbing against another surface.ASTM also has prescribed several methods to quantify abrasion resistance of textile materials these tests areASTM D 4966 -- 98 Standard Test Method for Abrasion Resistance of Textile Fabrics (Martindale Abrasion Tester Method)ASTM D 3884 Test Method for Abrasion Resistance of Textile Fabrics (Rotary Platform, Double-Head Method)3ASTM D 3885 Test Method for Abrasion Resistance of Textile Fabrics (Flexing and Abrasion Method)3ASTM D 3886 Test Method for Abrasion Resistance of Textile Fabrics (Inflated Diaphragm Method)3ASTM D 4157 Test Method for Abrasion Resistance of Textile Fabrics (Oscillatory Cylinder Method)3ASTM D 4158 Test Method for Abrasion Resistance of Textile Fabrics (Uniform Abrasion Method)3AATCC Test Method 93 Abrasion Resistance of Fabrics: Accelerator Method4In All of the above materials the tested specimen is rubbed is a particular manner against an abradent which may be a fabric, or a emery sheet or like for either a certain amount of time for for a certain number of strokes or cycles.At the end of the testing period , any change that may occur to the tested specimen normally 3 types of changes are looked for1. Mass Loss2. Color Change3. Hole formation or yarn breakageThe Earlier these changes occur the poorer the resistance to abrasion.Factors loke thickness of fabric, piles, any pretreatment to reduce or increace surface friction , etc all have a profound effect on the Abrasion resistance.In real life, trousers in case of apparel and Upholstery are subject to more abrasion than fabrics used in any other domestic use. In case of fabrics used for industrial application like belts etc are required to have very high abrasion resistance.ReferencesASTM International Book of Standards Volume 7.01 and 7.02AATCC Technical Manual - 2009
The durability of concrete is its ability to resist weathering action, chemical attack, abrasion, or any process of deterioration. The strength of concrete is the ability of the concrete to withstand pressure or force.
Abrasion resistance is typically measured using standardized tests such as the Taber Abrasion Test or the Martindale Abrasion Test. These tests involve subjecting the material to repeated rubbing or abrasion under controlled conditions to simulate wear and tear. The resistance of the material to abrasion is then quantified by measuring the loss in weight or thickness of the material after a specified number of abrasion cycles.
Polycarbonate is a common example of an abrasion-resistant plastic. It is known for its toughness and durability, making it ideal for applications where abrasion resistance is important, such as in protective eyewear or machine guards.
Yes, a smooth surface offers less resistance to abrasion or scratching compared to a rough surface. This is because a smooth surface has fewer irregularities or rough areas that can catch or snag against an abrasive material.
Since the typical abrasion affects only the skin, the term "wound" is likely to be considered an exaggeration. Wounds generally are deeper injuries than abrasions.
