摘　　要：在普通混凝土中掺加适量的减水剂和粉体等外加剂,可以改善混凝土的使用性能。通过室内试验,提出流态混凝土配制方法,同时,测定氯离子扩散系数和通电量对混凝土耐久性的影响。对混凝土向环保化、流态化、高强化和高效化发展起到促进作用。To improve the performance of concrete, proper superplastic and powder were mixed into common concrete as admixture. Through indoor test, the mixing technique of liquid concrete was summarized. At the same time, chlorine diffusion coefficient and charge passed which were measured indicated that the concrete had good durability. During the process from common concrete to the concrete with environmental protection, fluidization, high strength, high efficiency, the paper played a stimulative role.

关 键 词：流态混凝土 外加剂 耐久性
