4.1 The three test methods provide simulated abrasion conditions, which can be used to evaluate the effects on abrasion resistance of concrete, concrete materials, and curing or finishing procedures. They may also be used for quality acceptance of products and surface exposed to wear. They are not intended to provide a quantitative measurement of length of service. 4.2 The equipment used by each of these procedures is portable and thus suitable for either laboratory or field testing. The three procedures determine the relative wear of concrete surfaces as follows: 4.2.1 Procedure A—The revolving-disk machine operates by sliding and scuffing of steel disks in conjunction with abrasive grit. 4.2.2 Procedure B—The dressing-wheel machine operates by impact and sliding friction of steel dressing wheels. 4.2.3 Procedure C—The ball-bearing machine operates by high-contact stresses, impact, and sliding friction from steel balls. 1.1 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.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of each other. 1.3 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.
