Standard Test Method for Abrasion Resistance of Horizontal Concrete Surfaces
Importancia y uso:
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.
Note 2: Diagrams of three machines meeting these specifications are shown in Fig. 1, Fig. 2, and Fig. 3.4
