表面涂层材料对混凝土耐久性影响及应用研究

Research of the influence of surface coated material on durability of concrete and its application

基于混凝土耐久性破坏机理,本研究以刚性、柔性表面涂层材料对混凝土外表面进行防护处理,研究基准混凝土(即未进行表面处理的混凝土)与处理后混凝土的耐久性,根据试验结果和工程要求寻求最佳的表面涂层方案。研究结果表明,采用刚性表面涂层材料作面层、柔性表面涂层材料作底层的复合表面涂层是增强混凝土耐久性防护能力最有效的方法之一。

Based on the breaking principle of durability of concrete, we carried protective external coat on concrete with rigid and flexible coat materials and contrasted the durability between undealed and dealed concrete. We attempted to find the best project with the external coat according to the experiment results and the project requiring. Composite external coats are proved the one of the best method for enhancing the protecting ability of concrete - durability by the research result, which are composited by cover coats with rigid ones and the rough coats with flexible ones.
