高层大体积混凝土裂缝成因及控制措施

The Causes and Control Measures for the Mass Concrete Cracks in High-Rise Buildings

文章基于某工程筏板基础开裂原因,对大体积混凝土裂缝常见类型及其产生的原因进行阐述。重点论述了原材料、外加剂等对大体积混凝土温度裂缝控制的影响,以及在使用复合外加剂时需要考虑到相互之间的影响,并从原材料选取、施工组织设计等角度对大体积混凝土温度裂缝的防治措施进行阐述。

Based on the cracking causes of a raft foundation in a project,this paper expounds the common types of mass concrete cracks and their causes.The effects of raw materials,admixtures,etc.on temperature cracks of mass concrete are mainly discussed,and the mutual effects need to be considered when using composite admixtures.The prevention measures of mass concrete temperature cracks are expounded from the perspectives of raw material selection,construction organization and design,and so on.
