  • Research Brief: Evolving the C-S-H Packing Density at the Microscale 

    Petersen, Thomas; Ulm, Franz-Josef (2017-10-02)
    Cement paste is a complex multiphase material, roughly 50 percent of which, by volume, is composed of calcium-silicate-hydrates (C-S-H). The C-S-H phase, which lends the material its rigidity, appears to be a dispersion ...
