摘　　要：在阐述提高混凝土抗氯盐腐蚀的途径与机理的基础上,基于普通混凝土、复合掺和料与纤维混凝土等系列试验,重点研究各类掺和料对混凝土抗氯离子腐蚀的影响,在此基础上对高氯盐地区的混凝土掺和料进行优选,采用优化后的材料可以提高混凝土工程的质量,更好地服务于工程建设。The methods and mechanisms to improve the chloride corrosion resistance performance of concrete are presented. The influence of different admixtures on the chloride corrosion resistance performance of ordinary concrete, admixture-added concrete and fiber-reinforced concrete are studied by means of experiments. The admixtures for concrete used in chloride-rich area are optimized in accordance with the experiment results. With the optimized admixtures, the quality of the concrete is improved and the quality of the project is guaranteed.
