Three new publications available from American Concrete Institute

The American Concrete Institute (ACI) announces the availability of three new publications to educate and inform industry professionals on the newest concrete-related information and technology.

ACI members receive a discount (up to 40 percent) on all ACI publications. Publications can be ordered by calling 248-848-3800 or online at

The publications are as follows:

Guide for Lap Splice and Development Length of High Relative Rib Area Reinforcing Bars in Tension and Commentary (408.3R-09):  This guide is provided to help designers take advantage of higher bond strength exhibited by high relative rib area bars in the calculation of tension lap splice length and development length of bar reinforcement. It includes expressions for development and lap splice length applicable only for high relative rib area bars. This guide is available in hardcopy/printed or PDF format.

10th ACI International Conference on Recent Advances in Concrete Technology and Sustainability Issues (SP-261): This Symposium Publication contains the proceedings from the Tenth CANMET/ACI International Conference on Recent Advances in Concrete Technology, held in Seville, Spain, in Oct. 2009. The 21 papers include Durability of Ultra-High-Performance Concrete; Shrinkage Reducing Effect of a Combination of Internal Curing and Shrinkage Compensating Agents on High-Performance Concrete; and Geopolymer Concrete—Sustainable Cementless Concrete.

Ninth ACI International Conference on Superplasticizers and Other Chemical Admixtures (SP-262): This Symposium Publication includes 30 papers selected from a conference that took place in Seville, Spain, in Oct. 2009. Topics include Use of a Supplemental Agent to Improve Flowability of Ultra-High Performance Concrete; Performance of Superplasticizers in Blended Cement Systems; and Multifunctional Chemical Admixture to Reduce Quality Control Requirements of Self-Consolidated Concrete.
