A proposed new ASTM International standard will help minimize confusion in quantifying the texture value of a concrete surface. The standard — WK49335, Test Method for Concrete Micro Surface Texture — will be used to determine the smoothness/roughness of concrete surfaces as measured by a contact stylus instrument called a profilometer. The standard will describe how to use the profilometer and reliable data indexes, allowing users to quickly and precisely inspect the surfaces of 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. If you would like to help develop the standard, you are encouraged to become an ASTM member by signing up www.astm.org/JOIN.
The ASTM Committee E06 on Performance of Buildings’ next meeting is April 10-13, 2016 in San Antonio, Texas.
