工民建中混凝土裂缝成因以及控制措施

The concrete crack causes and control measures in civil construction

工民建施工中混凝土墙体裂缝的原因较多，大致分为自身形变、外载作用、化学作用以及养护不当，所以施工过程中要对其进行区分对待，根据实际情况采取相应对策。本文主要从工民建中混凝土裂缝产生的原因进行分析，介绍了原料选择、温度控制、施工技术等几方面防治措施，可降低工程使用阶段的风险系数，提升结构强度。

There are many causes of cracks on the concrete wall in civil construction, generally are itself deformation, external applied load effect, chemical action and improper maintenance, so during the construction process,they must be treated separately, based on the practical situation to adopt the corresponding countermeasures. This article analyzed the causes of civil construction concrete cracks, introduced several aspects of prevention and control measures like materials selection, temperature control,construction technology and others, could reduce the risk parameters of engineering service stage and improve the structural strength.
