The American Concrete Institute has Chapters and Student Chapters located throughout the world. Participation in a local chapter can be extremely rewarding in terms of gaining greater technical knowledge and networking with leaders in the concrete community. Chapter membership includes a diverse blend of architects, engineers, consultants, contractors, educators, material suppliers, equipment suppliers, owners, and students—basically anyone interested in concrete! In addition to technical programs and publications, many chapters sponsor ACI Certification programs, ACI educational seminars, project award recognition programs, and social events with the goal of advancing concrete knowledge. Domestically, chapters also host ACI conventions. Most chapters also maintain a library of ACI publications that is available to all chapter members at no cost.
