Cover Story: Multi-scale analysis of concrete requires validation and determination of input parameters at all scales. This paper presents techniques for making, testing and modelling micro-cubes of cement paste. The micro-cubes are made by precision cutting, grinding and micro-dicing. The microstructure is determined by X-ray tomography. Mechanical testing of the micro-cubes is performed by nano-indentation and the modelling is done by a lattice fracture model. View the paper
