New Method for Performance-Based Design of High-Performance Concrete
Proper design of HPC is very important for specific projects and applications. Due to the complexity of ingredients in contempary concrete, a new method for performance-based design of HPC based on least void and ternary factorial design approach was proposed. The fine to coarse aggregate ratio was determined according to the least void ratio after they were combined. The workability was determined by controlling water to binder ratio and the addition of chemical admixtures. The method based on the performance of portland cement-slag-fly ash ternary system was very efficient in determining the composition of concrete when multiple requirements need to be considered.
Dr. Caijun Shi received his B. Eng and M. Eng from Southeast University, Nanjing, China and his Ph.D from University of Calgary, Canada. He is currently a Chair Professor of College of Civil Engineering, Hunan University and China Building Materials Academy, Editor-in-Chief of 《Journal of Sustainable Cement-based Materials》, editorial board member of 《Cement and Concrete Research》,《Cement and Concrete Composites》, 《Materiales de Construccion》, 《Journal of Chinese Ceramic Society》,《Journal of Building Materials》,《Cement》, and former associate editor of 《 Journal of Materials in Civil Engineering》. Dr. Shi serves on many ACI and RILEM technical committees. His research interests include characterization and utilization of industrial by-products and waste materials, design and testing of cement and concrete materials, development and evaluation of cement additives and concrete admixtures, and solid and hazardous waste management. He has developed several novel technologies and products, and has been granted four US patents and ten Chinese patents. One of his inventions - self-sealing/self-healing barrier has been used as a municipal landfill liner in the world's largest landfill site in South Korea. He has authored/coauthored more than 200 technical papers, five English books, two Chinese books and edited/co-edited five international conference proceedings. In recognizing his contributions to researches in waste management and concrete technology, he was elected as a fellow of International Energy Foundation in 2001, and a fellow of American Concrete Institute in 2007.
