The American Concrete Institute (ACI) recently released two new documents on concrete slabs. 302.2R-06: Guide for Concrete Slabs that Receive Moisture-Sensitive Flooring Materials is a guide that contains materials, design, and construction recommendations for concrete slabs-on-ground and suspended slabs that are to receive moisture-sensitive flooring materials. Chapters provide an understanding of concrete moisture behavior and drying, and show recommended construction practices.

360R-06: Design of Slabs-on-Ground presents information on the design of slabs-on-ground, primarily industrial floors. The report also addresses the planning, design, and detailing of slabs. Background information on design theories is followed by discussion of the types of slabs, soil-support systems, loadings, and jointing. To order these and other publications, visit ACI's bookstore at
