水利工程施工中混凝土裂缝防治技术

Prevention and control technology of concrete crack in water conservancy construction

泥中游离氧化钙和氧化镁的熟化程度、混凝土热胀冷缩性能、施工过程中温差大是混凝土产生裂缝的主要原因。为提高施工质量,减少裂缝,施工过程中,应采取优化原材料配比、控制温差、加强管理等措施。

The curing degree of free calcium oxide and magnesium oxide in cement, the curing degree of free calcium oxide and magnesium oxide in cement, In the construction process, the temperature difference is the main reason for the crack of concrete. In order to improve the construction quality, reduce crack,during construction,measures should be taken to optimize the ratio of raw materials, temperature control, strengthening management and so on.
