摘　　要：依据普通混凝土力学性能和耐久性能试验方法国家标准,研究了清水饰面防护涂层对混凝土力学性能和耐久性能的影响,并讨论了清水饰面混凝土防护涂层的作用机理。结果表明:清水饰面混凝土防护涂层可有效地提高混凝土材料的力学性能和耐久性能,底层水泥漆主要通过聚合物改性增强底层涂层的力学性能和耐久性能,面层保护漆主要通过疏水效应和阻塞毛细孔效应提高涂层抵抗有害介质侵入的能力。The effect of fair-faced protective coating on mechanical properties and durability of concrete are studied by the national standards of mechanical properties and durability test method of concrete, and then the mechanism of fair-faced concrete protective coating are discussed in this thesis. The test results show that the concrete protective coating can improve the mechanical properties and durability of concrete. The mechanical properties and durability of cement paint are enhanced by polymer modified coatings, and its ability to resist the invasion of harmful medium is improved by the hydrophobic and blockage effect of surface layer of protective paint.
