防水混凝土在桥面铺装中的应用

Applications of Waterproofing Concrete in Bridge Deck Pavement

铺装层混凝土要具有足够的抗渗性能,在凝结硬化过程中少收缩或不收缩,以保证桥面在使用过程中不产生可透水的收缩裂缝,防止桥面积水下渗危及主梁。而防水混凝土的应用可以满足铺装层混凝土的要求。

The pavement concrete must have sufficient impermeability and little shrinkage or no shrinkage in the setting and hardening process, which can ensure the deck does not generate shrinkage cracks in the application process to prevent the deck water infiltration endanger the main beam. The application of waterproof concrete can make the requirements of the pavement layer of concrete.
