大体积钢筋混凝土施工中最常见的质量问题是混凝土裂缝。造成裂缝的原因是复杂的,而且是综合性的。其主要原因有:混凝土及原材料性能不良(如抗裂能力低、收缩大等),混凝土施工质量差(如不均匀性、养护不良等),结构形式及构造方面的问题 The most common quality problem in the construction of large volumes of reinforced concrete is concrete cracks. The causes of cracks are complex and comprehensive. The main reasons are: poor performance of concrete and raw materials (such as low crack resistance, large shrinkage, etc.), poor concrete construction quality (such as unevenness, poor maintenance, etc.), structural forms and structural problems
