The American Concrete Institute (ACI) is a nonprofit technical and educational society organized in 1904 and is one of the world's leading authorities on concrete technology. ACI is a forum for the discussion of all matters related to concrete and the development of solutions to problems. ACI conducts this forum through conventions and meetings; theACI Structural Journal, the ACI Materials Journal, Concrete International, and technical publications; chapter activities; and technical committee work. As its mission states, its purpose is to “Provide knowledge and information for the best use of concrete.”

This implies a willingness on the part of each member to contribute from his or her training and knowledge to the benefit of the public at large. By maintaining a high standard of professional and technical ability in its committee memberships and in the authorship of papers and publications, as well as in local chapter programs, ACI has contributed to a detailed knowledge of materials and their resulting structures.

ACI has chapters throughout the world. Participation in a local chapter can be extremely rewarding in terms of gaining greater technical knowledge and networking with other local members in the concrete community.

In addition to technical programs and publications, many chapters sponsor certification, educational, and project award recognition programs and social events with the goal of advancing concrete knowledge. Most chapters maintain a library of ACI publications that is available to all chapter members.

Chapters are a blend of architects/engineers, consultants, contractors, educators, material and equipment suppliers, owners, and students-virtually anyone interested in concrete
