| 摘 要： | 对当前混凝土早期裂缝日趋严重的原因进行了分析,提出了相关规范在抑制早期裂缝方面有待重新评估的内容,并通过早期收缩试验对早期收缩裂缝的控制进行了研究,认为加强初凝后的早期保湿养护是抑制这类裂缝产生的关键。

| Abstract: | The reason for increa.sin.gly serious early-age cracking of current concrete was analyzed.It was indicated that some criterions relating to inhibition of early-age cracking shoud be reappraised.Besides,the control of early-age shrinkage cracking was studied through early-age shrinkage experimentation and it was considered that the key for controlling early-age shrinkage cracking was enhancing early-age humid curing immediately after initial set. |
