摘要
砼工程中出现裂纹是典型的质量通病。砼裂纹不仅减少砼结构的使用寿命 ,而且给人们一种外观上的危险感。实践证明 ,只要严格按施工规范施工 ,抓好每一道工序质量 ,完全可以避免砼裂纹的产生。论述了砼裂纹产生的原因和机理 。
In concrete projects, crackles are common typical quality problems that do exist. Crackles not only shortened the service life of the concrete structure, but also led people to have a kind of risky feeling from its outward appearance. It had proved by practice that as long as concrete project was built strictly according to the construction standard, one should have paid attention to each working procedure and understood the cause and mechanism of the crackles and took some effective measures as well. One should also have the sense of how to prevent and cure it before hand, in this case, the concrete crackles can be avoided completely.
