关于消除大体积混凝土施工中温差裂缝的探讨

Thinking on eliminating large-mass concrete construction temperature-difference crack

结合工程实践,进行了大体积混凝土施工中混凝土温升的计算,从混凝土原料选用和施工技术两方面归纳了消除温差裂缝的措施,实践表明降低水化热、防止温度裂缝是保证大体积浇筑混凝土施工质量的关键。

Combining with project practice, the author calculates the concrete temperature rise in large-mass concrete construction, concludes the measures of eliminating temperature-difference crack from two points of the selection of concrete raw material and construction technology, practice shows that decreasing hydration heat and preventing temperature-difference crack is the key of ensuring large-mass pouting concrete construction quality.
