As strong as the wire itself. Test it yourself. With your bare hands pull apart most tack welded reinforcing sections. (It may only require a 20 lb. pull.) Now try this with any of the flush welded AA wire tie systems. It won't break! (Unless you can pull well over a thousand pounds.) Laboratory reports are available upon request. Remember a wire tie system is only as strong as the welds that hold it together. Be sure select from the full line of AA flush welded designs. Send for complete catalog.

Jerry Woods, Midwest regional construction superintendent for Portland Cement Association, demonstrates proper concrete finish ing techniques to visiting educators at a four-day seminar at PCA's Cement & Concrete Center in Skokie, III.
Concrete Construction Seminar Held
Modern concrete construction methods was the subject of a four-day seminar conducted by the Portland Cement Association for 20 professors of building construction in Skokie, III.
Seminar leaders were PCA engineers, architects, and marketing specialists. They discussed the latest develop- ments in concrete production, construction techniques, and teaching methods. Industry panels featured representatives of the construction industry who described applied inno- vations in concrete construction.
Seminar participants represented the engineering facul- ties of 17 U.S. colleges, universities, and technical institu- tions. Two were from the African nation of Ghana.
Uniframe Concrete Building System
Versatility in both design and application has been the key to the early success of Uniframe concrete building system developed by the Portland Cement Association. Uniframe is a precast rigid framing system for applications ranging from simple farm structures to large industrial plants and municipal buildings. The system was developed by PCA and extensively tested before franchised dealers were sought. The framing system makes use of three basic framing elements: L-shaped outside leg elements; Y-shaped legs for internal use in multi-bay applications; and inverted V-shaped beams for roof support. Connections are made by double bolted scarf-joints between legs and beams.
