Microstructure of cement-based systems/Bonding and interfaces in cementitious materials: symposia held November 28-December 1, 1994, Boston, Massachusetts, U.S.A.This book continues the MRS series on characteristics and properties of cementitious materials. In Part I, recent advances in microstructure and related characterization of cementitious systems are the focus. Topics include: microstructures of "normal" cement systems; microstructure of 'unusual' cement systems; image analysis, modelling and fractal analysis applications; and assessment of pore structures. Part II features presentations on interfacial microstructures, as well as information on elastic and fracture properties, transport properties, and the effects of interfaces on fiber-reinforced systems. |

Sometimes the quality and pureness of the used wastes are even better than
those of the equivalent natural primary resources, as there are typical products
like the fume purification residues. But normally the wastes used in this study are
...

This specimen is typical of ettringite mineralization in pore throats. C-S-H was
observed near fly ash grains. The core had moderately high strength, but also
relatively high permeability. Figure 3 shows a series of fracture surface
micrographs ...

Given any size distribution of particles and scale factors a, b, and c, the program
places a requested number of particles in a three-dimensional cubic volume,
typically 10 mm on a side, such that no particles overlap. The program proceeds
