大体积混凝土施工裂缝及防治措施

Crack and Preventive Measure of Mass Concrete Construction

大体积混凝土的施工技术要求比较高,在施工中要防止混凝土因凝固收缩、内外温差等原因产生的裂缝。结合工程实践,对大体积混凝土施工裂缝种类进行分析,从材料选择、混凝土浇筑、混凝土养护3方面提出防止裂缝发生的方法,并对施工中注意事项进行论述。

The mass concrete construction is relatively high technical requirements, in the construction to prevent concrete due to solidification contraction, internal and external temperature and other factors resuiting from the cracks. Therefore required from the material selection, technical support, process control and other relevant aspect of the job well can we guarantee the quality of mass concrete. Combination of practical work are some of the problems encountered in its construction process should pay attention to matters set out.
