Title: Modeling and Simulation of Cement Hydration Kinetics and Microstructure Development
Published: December 22, 2011
Abstract: This review endeavors to summarize the past 40 years or so of progress towards the development of mathematical models for understanding and predicting cement hydration behavior. A complete and accurate model of hydration would enable materials engineers not only to predict the performance of concrete in the field, but also to troubleshoot performance problems and even to help design new cementitious materials. Despite significant effort and progress, such a model has not yet been developed, mainly because cement hydration is one of the more complex phenomena in engineering science. Portland cement as we know it was invented nearly 200 years ago, but the processes that govern its reaction with water are still a matter of considerable debate, and several different theories are available for describing various aspects of hydration. A number of mathematical constructs have been developed to mimic hydration behavior, but these have generally focused on capturing changes in either select microscopic features or in the overall extent of hydration. Nevertheless, steady progress is being made toward a more comprehensive model description of hydration that describes both the development of microstructure and the kinetics.
