Standard Test Method for the Direct Measurement of Surface Profile of Prepared Concrete

Importancia y uso:

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.
