混凝土耐久性的研究与应用

The Research and Application of the Durability of Concrete

结合工程实例,研究了引气剂、膨胀剂、缓凝减水剂三者对混凝土耐久性的影响. 结果表明:采用三种外加剂配制的混凝土具有优良的抗冻融、抗渗和抗裂性能,满足混凝土建筑物耐久性要求,为海工混凝土的配合比设计以及耐久性能研究提供了新的途径和应用经验.

The effect of air-entering agent, expanding agent and water-reducing agent on the durability of concrete is studied with an engineering example. The results of the three agent admixtures show that they have excellent resistance to freezing, thawing cycling, permeability and cracking. The need of the durability of concrete buildings is satisfied. A new way for the study of admixture proportions and the durability of concrete used in ocean engineering is provided based on experience.
