American Concrete Institute
ACI publishes consolidation guide and two others. The American Concrete Institute announces the availability of three new publications.
347.2R-05, “Guide for Shoring/Reshoring of Concrete Multistory Buildings,” presents information and design criteria for shoring/reshoring operations during the construction of reinforced and post-tensioned multistory buildings. Topics include shoring/reshoring construction needs, construction loads on formwork, and strength adequacy of concrete slabs and formwork.
209.1R-05, “Report on Factors Affecting Shrinkage and Creep of Hardened Concrete,” describes the effects of numerous variables on shrinkage and creep of hardened concrete, including mixture proportions, environment, design, and construction.
309R-05, “Guide for Consolidation of Concrete,” includes information on the mechanism of consolidation and gives recommendations on equipment, characteristics and procedures for various classes of construction. Recommendations on mixture proportioning and vibration equipment are presented, as well as procedures for floor slabs, pavements, precast products, structural low-density concrete, high-density concrete, and self-consolidating concrete. The guide includes information on quality control and quality assurance.
These publications can be ordered at www.concrete.org or by calling (248) 848-3800.
