Roller-compacted concrete for dams and dam rehabilitation

The Portland Cement Association (PCA) and the Southeast Cement Association are co-sponsoring a technical seminar and site tour April 25-26, 2007, in Atlanta, demonstrating current trends in the use of roller-compacted concrete (RCC) for water resource applications. According to the PCA, the engineering community is increasingly recognizing RCC as an economical solution for rehabilitating existing dams and constructing new structures.

The seminar will provide information on the design of RCC mixtures, specifications, and quality control procedures. Speakers will present case studies on completed projects, as well as those currently under construction. Attendees also have the opportunity to visit nearby RCC projects, including a gravity dam and site that used RCC for an emergency spillway/overtopping protection of an earth embankment.

Attendees can earn 1.2 CEUs, as well as receive PCA design manuals. To register, call 847-972-9168; or register online at www.cement.org/water/rcc_seminar407.asp. Seminar registration is $175; a special rate of $140 applies to members of the Association of State Dam Safety Officials.
