本文设计试验了四种不同养护条件下,掺膨胀剂混凝土的自由膨胀效果以及限制膨胀效果,并与未掺膨胀剂的混凝土进行了对比试验。试验表明掺膨胀剂混凝土只有在充分的水养护条件下,才能发挥膨胀效果。
In this paper, we designed and tested the free expansion effect of expansive agent concrete and the effect of restraining expansion under four different curing conditions, and compared with the concrete without expansive agent. Tests show that expansive admixture concrete can only exert the expansion effect under sufficient water curing conditions.
