本文讨论美国混凝土学会308标准实践(ACI308 Stand Practice)中介绍的预测蒸发速度图解法,及减少混凝土塑性收缩开裂的可能性。举例介绍减少蒸发速度的一些必要措施。 在混凝土早期,只要我们提供合适的湿度和温 This article discusses the graphical method for predicting the evaporation rate described in the ACI308 Stand Practice and the possibility of reducing the plastic shrinkage and cracking of concrete. Examples of some of the necessary measures to reduce the evaporation rate. In the early days of concrete, as long as we provide suitable humidity and temperature
