High-Performance Concrete Program at the U.S. National Institute of Standards and Technology
J R. Clifton, G J. Frohnsdorff
The National Institute of Standards and Technology (NIST) is carrying out a collaborative program entitled Partnership for High-Performance Concrete Technology (PHPCT) to advance concrete technology and facilitate application of high-performance concrete (HPC) in building construction and the civil infrastructure. Its goal is to develop, and to implement, a computer-integrated knowledge system (CIKS) incorporating verified multi-attribute models for predicting and optimizing the performance and life-cycle cost of HPC. The underlying assumption is that the most effective and practical way of transferring the knowledge to potential users who are using, or considering using, new concrete technology, is to link the materials science of concrete to practice through an interoperable CIKS, consisting of databases, simulation models, and knowledge-based systems. This paper presents the outline of the PHPCT program which encompasses processing, materials characterization, performance prediction, structural performance, structural performance in a fire, and life-cycle costing of new technology materials; knowledge from all of these will be integrated in the CIKS which has been designated HYPERCON. Examples are given of prior and present HPC-related research at the NIST with the focus being on: cement characterization; flow properties of fresh concrete; simulation of microstructure development and transport phenomena; shear behavior; response of high-strength concrete to fire; and life-cycle costing of new technology materials.
