The effect of short duration NaCl exposure on the surface pore structure of concrete containing GGBFS

The purpose of this study is to evaluate the effect of chloride-binder interactions on the physical pore structure of concrete containing 0–60% ground granulated blast furnace slag (GGBFS) as cement replacement. Physical and chemical chloride binder interaction was measured based on chloride binder isotherms. Physical chloride binder interaction was estimated to be the difference between the total binding capacity and chemically bound chloride. …
