烟台地区混凝土冬季施工常见质量问题及防治方法

The Quality Problems and Antifreezing Measures of Winter Concreting in Yantai Area

针对烟台地区的气候特点，结合工程实际分析了砼冬季施工中易于出现的质量问题，受冻砼的特征及危害，并结合新浇砼的受冻机理及有关规范，讨论了实用防治措施，对工程事故处理及预防有较大的参考价值．

In connection with characterestic of Yantai area, the quality problems of winter concreting construction and the special features of frozen concrete are discussed. When the concrete is frozen, the harms to building also are expounded. Based on the depth analysis and reference national specifications, the antifreezing measures of winter concreting construction and the fresh concrete resists freezing in low tempereture are studied. The results may be referenced in structure engineering practice.
