大面积薄层混凝土裂缝成因分析及控制措施

Large Thin Layers Concrete Cracks Cause Analysis and Control Measures

大面积薄层混凝土极易出现裂缝,裂缝过多、过大会影响结构物的承载力和耐久性,还会增加维修费用,影响正常生产运营。在对仓库地面混凝土裂缝调查检测的基础上,结合温度应力计算、干缩应力计算,对仓库面层混凝土裂缝原因进行了深入分析,提出了裂缝控制技术措施,可以将裂缝的数量、宽度和深度控制到最小程度。

Thin layers of large concrete is very easy to crack,the more and larger cracks can influence the bearing capacity and durability of the structures,also can increase maintenance cost,affect the normal operation.Based on the investigation and inspection of concrete crack warehouse,combined with temperature stress,dry shrinkage stress calculation,the causes of concrete cracks on warehouse surface are analyzed,and puts forward the technical measures for crack control,the number,width and depth of crack can be minimized.
