| 摘 要： | 针对混凝土劣化的主要原因与机理,研究了混凝土碳化、水和盐溶液条件下的冻融破坏、硫酸盐物理结晶破坏与混凝土渗透性之间的相关关系。研究结果表明:混凝土的劣化与混凝土的渗透性能密切相关,以混凝土渗透特性作为基本参数评价和预测混凝土的劣化行为具有可行性。

| Abstract: | The relationship between damages of concretes such as carbonation,thaw and freeze under water and salt solution condition,sulfate crystallization corrosion and abrasion and permeation characteristics were analyzed in detail.Results indicate that there exists a close relationship between concrete deterioration and its permeability.It follows that penetration characteristic parameter can be used to evaluate the durability of concrete. |

| Keywords: | concrete deterioration permeability durability |
