Description New hydration products of ground granulated blast-furnace slag (GGBS) are formed during the hydration process of Portland slag cement concrete. Hydration of slag in concrete is accompanied by morphological changes and decrease of capillary porosity of C-S-H products. Spatial distribution of microcracks in concrete is related to chemical composition of new-formed slag hydrates. The permeability of concrete is one of the most important factors that influence the final durability of concrete.
