From the viewpoint of concrete critical strength, it proposed some suggestion to the concrete construction in winter considering the maturity of concrete.
混凝土约束改变了有效应力-应变关系：造成强度和临界应变的增加。
Confinement of concrete results in a modification of the effective stress-strain relationship: higher strength and higher critical strains are achieved.
本文简要介绍了用临界成熟度控制冬季施工混凝土强度增长的估算方法。
This paper briefly introduces the calculating method for controlling strength increase of concrete in winter construction with critical maturation degree.
再生混凝土是否存在临界受冻强度；
Whether the recycled concrete does exist critical frozen strength ;
试验还表明，当混凝土强度达到受冻临界强度后，随着负温值的增大其强度缓慢增长，弹性模量也有缓慢增长。
The experiment also shows that after the concrete strength reach the frost-resisting critical strength, its strength and elasticity module will increase slowly with the decrease of the temperature.
