Research on the Concrete Performance in the Marine Environment

This paper mainly studied effects of NaCl,MgSO4 soaking experiments,carbonation and freezing and thawing cycle on concrete intensity.The results show:When the concrete is completely soaked in chloride solution,the concrete of high slump of the same strength grade has high compressive intensity.With the improvement of the concentration of chloride ions solution,the chloride ion diffusion coefficient of concrete is increasing as well;for the structure in marine environment,low water-binder ratio and high mineral admixture can improve most of performances of concrete.
