Standard Guide for Abrasion Resistance of Mortar Surfaces Using a Rotary Platform Abraser

SIGNIFICANCE AND USE
5.1 Wear on mortar surfaces can be generated by a number of factors including skidding, scraping or sliding of objects on the surface, foot and tire traffic. This guide provides a means to quantify the abrasion resistance of treated or untreated mortars and other similar products.  
5.1.1 This guide can be used to determine the effectiveness of fluid applied hardeners, densifiers and sealers by comparison with untreated control specimens.  
5.1.2 This guide can be used with other test methods to determine the effectiveness of surface treatments after abrasion. For example, Test Method D6532 can be used to evaluate the effectiveness of clear water repellents on hydraulic cement mortar specimens based on water absorption after water soaking, by testing the specimen prior to abrasion and after the specimen has been subjected to abrasion.  
5.2 This guide may be useful for acceptance testing of a mortar surface, and it can be used to evaluate the effects of processing variables such as substrate preparation before treatment, surface texture, treatment application variables, and curing regimen.  
5.3 Results may be used to correlate with in-place performance, for comparative rating of the performance of alternative materials, or for comparison among treated and untreated surfaces. The resistance of material surfaces to abrasion, as measured on a testing machine in the laboratory, is generally only one of several factors contributing to wear performance as experienced in the actual use of the material. Other factors may need to be considered in any calculation of predicted life from specific abrasion data.  
5.4 The resistance of mortar to abrasion may be affected by factors including test conditions, type of abradant, pressure between the specimen and abradant, selection of mortar-making materials (mixture proportions, curing and finishing procedures), and type, kind, or amount of treatment materials.  
5.5 Abrasion tests utilizing the rotary platform abraser may b...
SCOPE
1.1 This guide is intended to assist in establishing procedures for determining the relative abrasion resistance of treated or untreated mortar surfaces.  
1.2 This 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.  
1.3 The 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.  
1.4 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.
