| 摘 要： | 通过实验,测试了拆模时间、膨胀剂掺量发生变化时混凝土的限制膨胀率,研究了拆模时间和膨胀剂掺量对限制膨胀率的影响变化规律。实验结果表明:在其他条件不变时,混凝土拆模时间越迟,其限制膨胀率越小;膨胀剂掺量越大,其限制膨胀率随之增大。

| Abstract: | By way of the experiment,the restrained-expansion rates of concrete with different form removal time,different concrete of expansion were tested,and the change rule of restrained-expansion rates was studied.The results indicate:the later the form removal time of concrete,the smaller the restrained-expansion rate;the restrained-expansion rate increased with the increase of expantion agent. |
