摘要
从混凝土临界强度的角度出发，结合成熟度在混凝土冬期施工的应用，提出了建议和说明。阐述了成熟度概念在施工中的应用方法，同时提出在自然条件下，估算混凝土已达到的强度与不同养护温度情况下，可以用等效龄期表达出相当于20℃养护温度下的历时时间，从而确保混凝土冬期施工的安全性。
From the viewpoint of concrete critical strength, it proposed some suggestion to the concrete construction in winter considering the maturity of concrete. It expounded the concept and the application of maturity in the construction, and put forward that it can use the equivalent age to determine the concrete maintenance duration of 20℃ based on the estimation to concrete strength and temperature in the natural condition. It can ensure the safety of concrete construction in winter.
