Significance and Use

4.1 Proper bonding of coatings and linings to concrete surfaces requires proper cleaning and frequently requires the concrete to be roughened to increase the surface area. The roughness, also known as surface profile, can be imparted into concrete by abrasive blast cleaning, acid etching or various impact/scarifying power tools. The resulting surface profile depth can influence coating/lining adhesion and performance. Coating/lining manufacturers or facility owners, or both, frequently specify cleaning and roughening of the concrete surface prior to product installation. The procedure described herein enables the user to quantitatively determine the profile directly from the prepared concrete surface in multiple locations. The procedure is similar to that described in Method B of Test Methods D4417, which addresses measurement of surface profile on abrasive blast cleaned steel surfaces.

Scope

1.1 This test method is suitable for both field and laboratory use to quantify the depth of surface profile of prepared concrete. It may also be used on unprepared concrete surfaces.

1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.3 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.

1.4 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, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
