The success of the 52-story One Shell Plaza building in Houston depended on the use of high strength lightweigth concrete. To achieve 600 psi lightweight concrete at the site for the mat foundation, columns, walls, and spandrels a rigorous quality control program was developed and followed through the entire project. The authors discuss the development of the design mix, tests made for establishing design criteria, and procedures for plant and field inspection to maintain quality control throughout the project. A checklist for quality control for future high-rise lightweight concrete buildings is propsosed.
