摘　　要：简要介绍北京建工集团在８０年代后期关于冬期综合蓄热法施工中，用成熟度推测混凝土早期强度的科研成果。在研究试验基础上提出强度０点更合理的推荐值，进一步完善了该方法，并就冬期施工养护混凝土的原则提出看法。In this article. there is a breif introduction of scientific research achievement obtained by the Beijing Building Construction Co. Consortium in the late 1980's during winter construction. By applying the heat-conservation method and taking maturity of concrete comprehensively that the concrete's early strength can be predicted. Through a number of experiments and researches. it has put-forward the more rational zeroaxial strength design, and furthermore bettered the prediction method. Besides, it has made some principles and suggestions for curing concrete during winter construction.
