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. FIG. 1 Rotary Platform Abraser FIG. 2 Arrangement of Rotary Platform Abraser Test Set-up 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 amo... 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, volume loss, or depth of wear. 1.3 The values stated either in SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. Some values have only SI units because the inch-pound equivalents are not used in practice. 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 The text of this standard refers to notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this standard. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards,...
Abstract
Overview
ASTM C1803/C1803M-23, titled Standard Guide for Abrasion Resistance of Mortar Surfaces Using a Rotary Platform Abraser, is an internationally recognized ASTM standard. It provides comprehensive guidance for measuring the abrasion resistance of both treated and untreated mortar surfaces using a rotary platform abraser. This testing method is critical for assessing how mortar products withstand wear caused by factors such as foot traffic, tire contact, scraping, or sliding objects. The guide also facilitates the evaluation of the effectiveness of surface treatments, such as hardeners, densifiers, and sealers, ensuring that construction materials meet durability expectations in both commercial and industrial applications.
Key Topics
- Abrasion Resistance Testing: Evaluates how mortar surfaces resist wear and tear using a rotary platform abraser that combines rolling and rubbing actions.
- Quantifiable Results: Abrasion can be measured by cycles to a specific end-point, mass loss, wear index, volume loss, or depth of wear.
- Comparative Analysis: Enables direct comparison between treated surfaces and untreated control samples to determine the effectiveness of surface treatments.
- Evaluation of Surface Treatments: Used to assess performance improvements provided by fluid-applied hardeners, densifiers, and sealers.
- Effects of Processing Variables: Considers how substrate preparation, surface texture, application methods, and curing regimens impact abrasion resistance.
- Test Standardization: Requires the use of either SI or inch-pound units, but these should not be intermixed.
- Comprehensive Reporting: Outlines requirements for documenting material proportions, testing conditions, treatment types, and evaluation criteria.
- Optional Criteria: Provides guidance for additional evaluation methods including mass loss, wear index, volume correction for density, and depth of wear.
Applications
The ASTM C1803/C1803M-23 standard is widely applied across various sectors for quality control and research in construction and material science, including:
- Construction Quality Assurance: Used during acceptance testing of mortar surfaces to verify compliance with wear resistance specifications for flooring, pavements, sidewalks, and industrial floors.
- Surface Treatment Evaluation: Assists manufacturers and contractors in determining the effectiveness of hardeners, sealers, or water repellent treatments under abrasion conditions.
- Material Comparison: Enables comparative rating of different mortar mixtures or surface treatments to select the best performing solution in terms of abrasion durability.
- Performance Prediction: Provides laboratory data that can correlate with real-world in-place performance, supporting life-cycle and maintenance planning for concrete structures.
- Research and Development: Informs decision-making about material improvements by assessing the impact of different aggregate choices, mixture proportions, and curing methods on abrasion resistance.
