摘要
现代混凝土在不断取得技术进步的同时,裂缝问题尤其是早期开裂一直困扰着工程界。早期裂缝主要是收缩所致,本文在阐述裂缝控制原则的基础上,着重从结构、材料两方面对早期收缩裂缝的控制提出了一些措施,以期对这一问题的解决起到一定的借鉴。
The problems of cracking have been bothering the engineers all the time,even when the technology of concrete makes continuous progress.The early-age cracking is mainly caused by shrinkage.The measures of reducing shrinkage cracking are proposed in the paper based on illuminating the principle to control cracking,including structural measures and material measures.It is expected to be helpful to solve the problem.
