混凝土的裂缝问题是一个普遍存在而又难以解决的工程实际问题。混凝土结构裂缝可分为微观裂缝和宏观裂缝。微观裂缝是指那些肉眼看不见的裂缝,主要分为三种:一是骨料与水泥石粘合面上的裂缝,称为粘着裂缝;二是水泥石中自身的裂缝,称为水泥石裂缝;三是骨料本身的裂缝,称为骨料裂缝。微观裂缝在混凝土结构中的分布是不规则、不贯通的。反之,肉眼看见的裂缝称为宏观裂缝,这类裂缝的范围一般不小于0.05mm,
Concrete crack problem is a ubiquitous and difficult to solve practical engineering problems. Concrete structure cracks can be divided into micro-cracks and macro-cracks. Micro-cracks are those invisible to the naked eye, mainly divided into three types: First, aggregate and cement bonded surface cracks, known as sticking cracks; Second, cement stones in their own cracks, known as cement cracks ; Third, the aggregate itself cracks, known as aggregate cracks. The distribution of microscopic cracks in concrete structures is irregular and not continuous. On the contrary, the naked eye to see the cracks known as the macro, the scope of such cracks generally not less than 0.05mm,
