| 摘 要： | 本文结合工程实例介绍了预拌加冰混凝土的温度计算公式和理论用冰量的计算公式．提出了在不同气温条件下应分别采取一种或多种温控措施(水泥预冷却、砂石冲洗、加冰水或碎冰搅拌等)以控制混凝土的入模温度，并推导得出了预拌加冰混凝土的最低入模温度极限值。

| Abstract: | Based on engineering examples, the temperature and theoretic ice dosage calculating formulae of ready-mixed iced concrete are introduced in the paper. In order to control the concrete molding temperature, one or more measures(pre-cold-ing of cement, water washing of aggregate, batching with iced water or ice pieces), should be adopted according to different air temperature. The lowest molding temperature of ready-mixed iced concrete at certain condition is also deduced in the paper. |
