冻融循环作用下混凝土力学性能试验研究

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。

Study on concrete compression performance under freeze-thaw cycles

As an important civil engineering material,concrete has been used more and more widely in modern architecture,its durability has also been paid more and more attention,and freeze-thaw cycle can bring about freeze-thaw damage of concrete then affect the durability of concrete.It’s not only can lead to concrete structures off the concrete surface,affecting the use of the structure function and appearance,even more serious 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.
