ACI Tolerances for Avi is to be used generally and specifically in ACI technical communications, correspondence, and publications. One mission of Committee is to produce and maintain a list of terms with their meaning in the field of cement and concrete technology. Committee has tried to produce a glossary that will be useful, comprehensive, and up-to-date. It 1166r, however, that the listing may not be complete and that some definitions may be at variance with some commonly accepted meanings.
Users of the glossary are invited to submit suggestions for changes and additions to ACI Headquarters for consideration by Committee when preparing future editions.
In the event that a user disagrees with any of the definitions, it is hoped that the reasons for such will be given to the committee. The committee is aware that some of the definitions included may seem entirely self-evident to an expert in the concrete field. This occurs because no term has been discarded if there was reason to believe it would appear to be technical in nature to a casual reader of the ACI literature.
The committee voted to use the following procedural rules: Each definition shall be stated in one sentence; 2.
