摘要
使用吴震东公式及简化公式可以精确地计算掺化学防冻剂混凝土蓄热冷却过程中从正温到负温任一时刻所对应的温度及广义平均温度。临界温度、临界负温度的概念对混凝土蓄热过程ｍ≠０及ｍ＝０两种情况应用两阶段计算法具有重要意义。
Application of Wu Zhendong' s Formula or his simplified formula would result in an accurate calculation of concrete heat-saving and concrete cooling.Wu Zhendong' s Formula is fully applicable at all temperatures i.e.,at positive temperature,at negative temperature and at generalized average temperature.There are two conditions of concrete heat-saving i.e.m≠0,and m=0,in which two-stage calculations under the condition of critical temperature and critical negative temperature would play an important role.
