Full title and description

ASTM C1803/C1803M-23 — Standard Guide for Abrasion Resistance of Mortar Surfaces Using a Rotary Platform Abraser. This guide describes procedures for determining the relative abrasion resistance of treated or untreated mortar surfaces using a rotary platform abraser (Taber-type) and gives common evaluation end-points such as cycles to an end-point, mass loss, wear index, volume loss, or depth of wear.

Abstract

This standard guide establishes recommended procedures for preparing mortar specimens, operating a rotary platform abraser, selecting test parameters, and recording results to compare abrasion resistance of mortar surfaces. The guide is intended for comparative evaluations rather than absolute service-life predictions; it documents several common metrics (cycles to a specified endpoint, mass loss, wear index, volume loss, depth) and references related ASTM and other abrasion test methods for complementary use.

Scope

This guide is intended to assist in establishing procedures for determining the relative abrasion resistance of treated or untreated mortar surfaces using a rotary platform abraser that produces combined rolling and rubbing wear. It covers selection of test parameters, specimen preparation and conditioning, common end-points and evaluation metrics (cycles to end-point, mass loss, wear index, volume loss, depth of wear), and notes other methods that may be of interest. Values are stated in either SI or inch-pound units (each system to be used independently).

Key topics and requirements

• Use of a rotary platform abraser (Taber-type) to generate combined rolling and rubbing action on mortar specimens.
• Specification of specimen preparation, surface treatment, and conditioning before testing.
• Definition of test parameters: abrasive wheels/discs, applied load, speed, and cycling protocol.
• Common evaluation end-points: cycles to a defined visual or dimensional end-point, mass loss, wear index, volume loss, or depth of wear.
• Guidance on reporting results and using SI and inch-pound units independently.
• Reference to other ASTM and industry abrasion methods for concrete and related materials.

Typical use and users

This guide is used by materials and quality laboratories, mortar and cement manufacturers, coatings and surface-treatment developers, flooring and paving specifiers, research organizations, and construction quality-control personnel who need to compare abrasion resistance of mortar surfaces or assess effects of surface treatments. It is intended primarily for comparative testing rather than direct prediction of in-service lifetime.

Related standards

ASTM C1803/C1803M-23 references and is related to several test methods and specifications for abrasion and surface wear, including (but not limited to) ASTM Test Methods C418, C779/C779M, C944/C944M, C1138M, C1353, and related methods such as ASTM D4060 and F510, and Specification C744. These complementary standards provide alternative abrasion procedures, specimen types, or metrics applicable to concrete, mortar, coatings, and flooring.
