Proposed ASTM Test Method Will Measure Surface Smoothness/Roughness of Concrete


A proposed new ASTM International standard will help minimize confusion in quantifying the texture value (smoothness/roughness) at the surface of concrete.

The standard (WK49335, Test Method for Concrete Micro Surface Texture) will be used to measure concrete surfaces with a contact stylus instrument (profilometer). It will describe how to use the profilometer and reliable data indexes, allowing for fast and precise surface inspection on a wide range of cement-based building materials, such as concrete flooring.

The technology described in the proposed standard will be used to provide an accurate assessment in surface irregularities and serviceability of concrete. The test described will be particularly relevant to people in the decorative concrete industry, which is currently not guided by a standard that addresses concrete finishes. 

ASTM Subcommittee E06.21 on Serviceability is developing the new standard and encourages all interested parties to join them.

ASTM welcomes participation in the development of its standards. Become a member at
