ASTM International’s Subcommittee E06.21 has suggested a new test method to help minimize the confusion in quantifying texture value at the concrete surface.

WK49335, Test Method for Concrete Micro Surface Texture will be used to measure concrete surfaces with a contact stylus instrument—a profilometer. This will allow a fast and precise surface inspection on a wide range of cement-based building materials. The process provides an accurate assessment in surface irregularities and serviceability of concrete.

The test will be relevant to people in the decorative concrete industry, which is currently not guided by a standard that addresses concrete finishes.
