Abstract

The interfacial transition zone in concrete; experiment versus computer simulation P. Stroeven Faculty of Civil Engineering and Geosciences Delft University of Technology, The Netherlands Abstract Interfacial transition zones (ITZ) between aggregate particles and bulk paste play a major role in short-term and long-term behaviour of cementitious composites. Ample experimental data, obtained by different methods and measuring different features, do not offer a coherent perspective on the ITZ, unfortunately. The 'realistic' computer-simulation approach presented provides at least a qualitative basis for interpretation of the various experimental data depending on their configuration-sensitivity. Sources for differences between experiment and simulation are discussed. 1 Introduction Cementitious materials can be considered consisting of particulate elements on the various levels of the microstructure. Particularly relevant for physico- mechanical properties is the packing o
