混凝土的早期收缩裂缝是化学收缩、干燥收缩共同作用的结果。其形状无规则 ,深度、宽度表现不一 ,是建筑工程急待解决的一个普遍问题。虽说可以通过多种方法对混凝土的收缩裂缝进行处理 ,但裂缝的产生对钢筋锈蚀、混凝土的耐久性总会带来不利影响。因此 ,避免混凝土产生早期收 Early shrinkage cracks in concrete are the result of a combination of chemical shrinkage and drying shrinkage. Its shape is irregular, and its depth and width vary. It is a common problem that urgently needs to be solved in construction projects. Although a variety of methods can be used to treat shrinkage cracks in concrete, the occurrence of cracks can adversely affect the corrosion of steel bars and the durability of concrete. Therefore, avoid early production of concrete
