文中首先介绍了补偿收缩混凝土抗裂防渗的原理。之后着重讨论了当前最主要几种膨胀剂的组成、膨胀原理、性能,并以工程实例阐述了用膨胀剂配制补偿收缩混凝土在结构自防水、大体积混凝土结构、特种结构、刚性屋面防水等方面的应用。
In this paper, the principle of crack-resisting and anti-seepage concrete for compensation shrinkage is first introduced. Afterwards, the composition, expansion principle, and performance of the most important expanding agents are discussed in detail, and an engineering example is used to describe the use of expansion agents for the preparation of compensation-shrinkage concrete in structural self-waterproofing, mass concrete structures, special structures, and rigid roof waterproofing. Applications.
