Full Description

1.1This guide is intended to assist in establishing procedures for determining the relative abrasion resistance of treated or untreated mortar surfaces.

1.2This guide utilizes the rotary platform abraser, which generates a combination of rolling and rubbing to cause wear to the specimen surface. Wear can be quantified as cycles to a specific end-point. Other commonly used evaluations are presented in Appendix X1 and include mass loss, wear index, or volume loss.

1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Note 1:Other procedures used to measure abrasion resistance of concrete surfaces include Test Methods C418, C779/C779M, C944/C944M, and C1138M. Other methods that reference the rotary platform abraser and may be of interest include Specification C744 and Test Methods C1353, D4060 and F510.

1.4This 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.
