Test Method for Abrasion Resistance

2017-10-10 15:38

There are number of different tests used in various countries and it is clear that there is no single test that adequately measures the abrasion resistance of concrete under all conditions. This paper covers the summary and classification of the various abrasion tests which are listed below.

This test method covers three procedures for determining the relative abrasion resistance of horizontal concrete surfaces. The procedures differ in the type and degree of abrasive force they impart, and are intended for use in determining variations in surface properties of concrete affected by mixture proportions, finishing, and surface treatment. They are not intended to provide a quantitative measurement of the length of service that may be expected from a specific surface.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of each other.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.When abrasion is the predominant factor causing deterioration of your materials, testing will give you data to compare materials or coatings and can help you predict the life time of a material or coating.

Abrasion testing is used to test the abrasive resistance of solid materials. Materials such as metals, composites, ceramics, and thick (weld overlays and thermal spray) coatings can be tested with this method. The intent of this test method is to produce data that will reproducibly rank materials in their resistance to scratching abrasion under a specified set of conditions.

The test should not be used to predict the exact resistance of a given material in a specific environment. Its value lies in predicting the ranking of materials in a similar relative order of merit as would occur in an abrasive environment. Volume loss data obtained from test materials whose lives are unknown in a specific abrasive environment may, however, be compared with test data obtained from a material whose life is known in the same environment. The comparison will provide a general indication of the worth of the unknown materials if abrasion is the predominant factor causing deterioration of the materials.
