ACI has over 94 chapters, 244 student chapters, and 30,000 members spanning over 120 countries. The history of any organization is a reflection of the ideals and activities of individuals or organized groups within it, and their influence on the accomplishment of the established objective or its revision to meet changing conditions. So it has been with ACI and its antecedent, the National Association of Cement Users. This brief account attempts to point out significant developments that have guided the Institute to its present position. Space does not permit naming all the "greats" who have contributed so generously of time and effort to ACI work and progress of the industry. The history of ACI is, of course, closely tied to the history of developments in concrete technology. This development is recorded as it occurred in the pages of the Institute's publications.
