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 1960’s,
and revised in 1982. With the introduction of computerized library
software in the early 1990’s, 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. It ensures that authors
of research reports, database compilers, and others use consistent
terminology when documenting or indexing the material, so that end
users can retrieve needed information more efficiently.
Unlike a simple list of accepted keywords, a thesaurus is a hierarchical
list. That is, it displays not only the terms, but also the relationships
to other terms--Broader, Narrower, or Related. A Thesaurus also
provides cross references from synonyms to the “official”
terms.
EXAMPLES:
Efflorescence
- Broader terms: Surface defects
- Related terms: Weathering, Leaching, Staining…
Lightweight aggregates
- Narrower terms: Polystyrene beads, Perlite,
Vermiculite…
Exposed Aggregate Concrete
- Used for: Aggregate transfer method
- Broader terms: Architectural concrete
- Related terms: Concrete finishing, Concrete
finishes, Decorative aggregates
Flowable Fill
- Use: Controlled Low-Strength Materials (CLSM)
Microsilia
Young’s modulus
- Use: Modulus of elasticity

The PCA Thesaurus
is (and always will be) a “work in progress,” due to
the continuous introduction of new materials and technologies. We
welcome any suggestions for changes! Please send them to Bill Burns,
e-mail wburns@cement.org,
or Connie Field, e-mail cfield@cement.org.
