SPECIAL TOPICS IN CONCRETE PLACEMENT. PUMPING HIGH-STRENGTH CONCRETE ON WORLD'S TALLEST CONCRETE BUILDING
The article describes how a single concrete pump and separate placing bom placed almost all of the concrete for the 79-story South Wacker Tower in Chicago. Concrete mixes, containing high-range water reducers and silica fume to develop ultra high strengths, were combined with a post-tensioned floor design to speed the construction. Details of the pumping are briefly described, and other highlights of the construction are noted.
