Procedure for Determining Conformance to Concrete Surface Profile Requirements
This standard describes the number of locations that should be measured to characterize the entirety of the prepared surface using Method 1: Depth micrometer as described in ASTM D8271, Method 2: Concrete Surface Profile (CSP) Chips (CSP 1-10) as described in ICRI Guideline No. 310.2R, or Method 3: Replica putty as described in ASTM D7682 (Method 3A-visual or Method 3B-quantitative).The surface profile (roughness) of prepared concrete can be assessed visually using CSP Chips such as those described in Guideline No. 310.2R produced by the International Concrete Repair Institute (ICRI), or by creating a replica of the prepared surface using an epoxy putty as described in ASTM D7682 and comparing it to the specified ICRI chip (Method A) or taking depth micrometer measurements from the replica (Method B). ASTM D8271 describes a procedure for acquiring measurements directly from the prepared concrete using an electronic depth micrometer. The Technical Applications for Concrete Materials (TACM)(1) group also produces concrete samples that are mechanically (or chemically) processed by the actual methods used to obtain the ICRI CSP® profiles.
