PCA Cement and Concrete Thesaurus

"The PCA Cement and Concrete Thesaurus, a list of accepted terminology for all aspects of cement and concrete, can now be accessed online. The Thesaurus was first compiled by PCA staff in the 1960s, and revised in 1982. With the introduction of computerized library software in the early 1990s, it became possible to reexamine and update the Thesaurus more efficiently, allowing the addition of hundreds of new terms and other changes as new materials have been cataloged. A thesaurus has a very practical purpose.
