随着我国城市化进程的高速推进,混凝土的应用范围迅速扩大。在比较恶劣的使用环境条件下,混凝土虽能满足强度要求,但因耐久性不良而遭到破坏的工程实例比比皆是。这些破坏所造成的经济损失极为可观。于是,提高混凝土耐久性的研究也成了一个重要课题。本文从抗磨损、抗硫酸盐腐蚀、抗碳化及抗碱-集料反应等方面讨论如何提高混凝土耐久性。
With the rapid progress of urbanization in our country, the scope of application of concrete is rapidly expanding. In the harsh environment of use, although the concrete can meet the strength requirements, but due to poor durability damaged projects abound. The economic damage caused by these damages is extremely substantial. Therefore, to improve the durability of concrete research has become an important issue. This article discusses how to improve the durability of concrete from aspects of anti-wear, anti-sulfate corrosion, anti-carbonation and anti-alkali-aggregate reaction.
