About Us

The Missouri Chapter is dedicated to encouraging the objectives for which the American Concrete Institute (ACI) was organized: to further engineering & technical education, scientific investigation & research and development of standards for design & construction of concrete structures.

This Chapter operates to support students, engineers, contractors and material suppliers in the concrete industry. The Chapter provides ACI Certification, seminars on concrete related issues and financial support for Students, Students Chapters and ACI International. We also support related organizations within the industry.
