【摘要】 通过氯离子迁移渗透试验和冻融损伤后氯离子扩散深度试验,研究自密实混凝土抗氯离子扩散的性能和冻融损伤对氯离子扩散能力的影响。结果表明,自密实混凝土较普通混凝土具有良好的抗氯离子扩散和冻融损伤能力,可提高抵御氯盐侵蚀能力,防止钢筋锈蚀,增强混凝土耐久性。更多还原

【Abstract】 Starting from the chloride migration permeability and chloride diffusion depth test,the influence of SCC anti-chloride diffusion ability and the freeze-thaw damage on the chloride diffusion performance is studied.The results show it is notable that chloride diffusion performance and freeze-thaw damage ability from the SCC compared with concrete.The SCC are better improve reinforcement corrosion and concrete durability.更多还原
