A nanochemomechanical investigation of carbonated cement paste

[摘要] (cont.) The characteristic size of the calcium carbonate is below the micron scale, while the silica gel often reaches up to 10-20[mu]m in extension. The microstructure of these products is highly disordered. We arrive at these conclusions as the result of a dual chemical-mechanical analysis at the nanoscale in which statistical electron probe microanalysis (EPMA) and statistical nanoindentation analysis are employed. The development of a statistical EPMA method for cementitious materials is an original method of this thesis.
