| 摘 要： | 研究了空白混凝土、单掺FA、单掺SF及FA与SF复合的混凝土在水胶比为0．35，龄期为28d时抗冻和冻融前后抗氯离子渗透的性能。试验结果表明：矿物掺合料对混凝土抗冻及抗氯离子渗透的性能均有较大影响；混凝土抗冻性与抗氯离子渗透性有一定相关性；适量的SF与FA复合是获得抗氯离子渗透及抗冻性能较好的混凝土的有效途径之一。

| Abstract: | The capability of chloride permeability and frost - resistant of concrete, concrete with FA, concrete with SF and concrete with SF and FA , in 28 days as well water binder rate 0.35, was studied. It is showed that the mineral admixture can take much influence on the capability of chloride permeability and frost - resistant. There are some relationships between chloride permeability and frost - resistant. Concrete with proper FA and SF is one of the best ways to improve capability of chloride permeability and frost - resistant of concrete. |
