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.

What are the disadvantages of low carbon steel?
Abrasion resistance is low.
What are differences between durability and strength of concrete?
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.
Why it is need to use high strength concrete in prestressed concrete?
to offer high resistance in tansion,shear and bond
What is the typical bulk resistance of rectifier diodes?
101902kb ohm
What is tumble index?
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.
What is abrasion resistance?
abrasion resistance is the resistance in abrasion
What has the author Massud Sadegzadeh written?
Massud Sadegzadeh has written: 'Abrasion resistance of concrete'
What are two words for friction?
Abrasion, Resistance
What is unit of abrasion resistance?
Mohs scale
What are the disadvantages of low carbon steel?
Abrasion resistance is low.
What is a typical textile abrasion resistance?
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
What is the abrasion resistance of marble?
It should be minimum 10 according to ASTM C 503.
How has kevlar been improved over the years?
Kevlar has improved the abrasion resistance, tear strength, modulus, chip resistance and rubber strength.
What are differences between durability and strength of concrete?
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.
Is an abrasion an open wound?
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.
Is silicon carbide is used for increasing the impact strength of the material?
No. Silicon carbide is used for abrasion resistance and traction.
What best defines plasticity when working with concrete?
determines concrete's ease of molding or resistance to deformation
