谈降低混凝土收缩与温度应力的措施

Reduce the shrinkage and temperature stress in concrete through proper construction measures

阐述了新浇筑的混凝土在凝结、固化过程中体积不断缩小及在温度发生变化时的热胀冷缩性质。通过设置伸缩缝、后浇带、掺混凝土外加剂等措施 ,减小了混凝土结构内部的应力与应力引起的破坏 。

In this paper the thermal expansion and cool shrinkage characteristics in condensation and solidification process of depositing concrete are elaborated. Through setting up expansion joint, late poured band and using concrete admixtures a serials measures are proposed to reduce internal stress and the failures caused by those stresses.
