摘要
混凝土裂缝影响着混凝土的外观质量、强度和耐久性 ,进而影响混凝土建筑物的使用和寿命。分析了混凝土裂缝产生的原因 ,主要有塑性变形、温度变形、干缩变形、碱骨料反应、碳化及钢筋锈蚀、地基沉降、设计及施工不当所造成的裂缝等 。
The appearance quality,intensity and durability of concrete are affected by concrete crack, which then affects the service life of buildings. In the paper the causes of concrete cracking are analyzed,including plastic,temperature and shrinkage deformation,AAR,carbonization and concrete bar rustiness, foundation sedimentation and load. In the end some preventive measures to cracks are proposed.
