We expect to try three methods of producing a wear-resistant floor. Where can we find a laboratory in our area that is competent to run wear tests on concrete?
The American Council of Independent Laboratories provides a list of testing services offered by its members. These have been tabulated in the December 1976 issue of Concrete Construction, page 647. The information is listed by area, so it is easy to choose laboratories on the basis of location. The list can be used for most other laboratory services as well as wear testing.
