| Abstract: | NEL method was adopted to measure the chloride ion diffusion coefficient. The effects of different additions of fly ash and different mixing processes of concrete on permeability of chloride ion were studied. Proper addition of fly ash or secondary mixing process can improve the mechanical properties and durability of the concrete efficiently. |
