温度对碱一集料反应的影响遵循Arrhenius方程,混凝土制品初期养护能大大加速其中的碱-集料反应,80℃10小时的蒸养会使得碱-集料反应程度相当于20℃下养护数月的结果。蒸气养护还使得混凝上膨胀静止期大为缩短,促进碱-集料反应膨胀的发展。
The effect of temperature on the alkali-aggregate reaction follows the Arrhenius equation. The initial curing of concrete products can greatly accelerate the alkali-aggregate reaction. The 10-hour steaming at 80°C will cause the alkali-aggregate reaction to be equivalent to that at 20°C. The result of the month. Vapor curing also greatly shortens the expansion and quiescent period of coagulation and promotes the development of alkali-aggregate reaction expansion.
