Abstract: When completed in 2009, Trump International Hotel and Tower, Chicago will rise to a height of 345 metres (415 metres including the spire). Designed by Skidmore, Owings & Merrill LLP (SOM) the 92-story Trump Tower will be the tallest concrete building in the United States, and the tallest building built in North America since the completion of Sears Tower in 1974.
New ground is being broken through a series of high performance concrete mixes designed by Prairie Material Sales, Inc. and employed by SOM on the project. Local areas in the outrigger zones require 110 MPa concrete at 90 days. Since this 110 MPa concrete is also located in areas of high reinforcement congestion, self-consolidating concrete has been specified for the mix. It is also necessary to limit the heat gain during the hydration process as this concrete is used in the massive outrigger elements. It is the first application of 110 MPa self-consolidating concrete pumped and placed to an elevation up to 200 metres above grade. The high performance SCC mix includes multiple cementitious constituents including slag cement, fly ash, silica fume, and ordinary portland cement.
