摘要
混凝土作为重要的土木工程材料,在现代建筑中运用的越来越广泛,其耐久性研究也得到越来越多的重视,冻融循环可以造成混凝土的冻融损伤进而影响混凝土的耐久性能,不仅可以导致混凝土结构构件表面混凝土脱落,影响结构的使用功能和外观,更严重的是使混凝土的强度降低,使构件承载力降低,主要对不同等级的混凝土试块进行冻融循环试验,通过力学性能试验研究冻融循环对混凝土耐久性的影响,为混凝土耐久性研究提供依据。
As an important civil engineering material, concrete has been used more and more widely m modem arcmtecture, its auraomty nas also been paid more and more attention, and freeze-thaw cycle can bring about freeze-thaw damage of concrete then affect the durability of con- crete.It＇s not only can lead to concrete structures off the concrete surface, affecting the use of the structure function and appearance, even more se- rious is reduce the strength of the concrete then reduce the capacity,mainly study the different grades of concrete block to freeze-thaw cycle test, by mechanical testing to study the impact of freeze-thaw durability on concrete ,provide the basis for the durability of concrete.
