The physics of cement cohesion
Webb31 jan. 2011 · Molecular simulation studies and direct-force measurements by atomic force microscopy provide strong arguments for predicting that short- and medium-range … Webb1 juli 2014 · The present work aims at quantitatively evaluating the cohesion (post-peak) strength of a common concrete and a micro-concrete and proposing a modelling of their softening behaviour. To achieve this goal, several spalling tests have been performed to damage without breaking the specimen.
