The two important factors of affect concrete durability are AAR (Alkali aggregate reaction) and freeze-thaw cycles.
碱骨料反应和冻融循环是影响混凝土耐久性的两个重要因素。
The results of durability test show its service life has been over 100 cycles, so the problems mentioned above have been overcome.
耐用性试验的结果表明，使用寿命已超过100次，从而解决了上述的问题。
The concrete with this product has excellent anti-frost durability, with a relative dynamic elastic modulus of 97% after 300 cycles of freezing-and-thawing.
混凝土抗冻融300次时，动弹性模量为97%，混凝土具有优良的抗冻融耐久性。
So it is important to the reinforced concrete structures exposed in salt environment and subjected to freezing and thawing cycles for the durability design.
所以，对于盐环境中经受冻融循环作用的钢筋混凝土结构，加强其耐久性设计非常重要。
Note:For GB14048.1-2006, the term "durability"expresses the expectancy of the number of operating cycles which can be performed by the equipment before repair or replacement parts.
注：根据GB14048.1-2006，术语“寿命”表示电器在修理或更换部件前能完成的操作循环次数的概率。
