| 摘 要： | 掺有天然火山灰的碾压混凝土拌合物的初凝时间较基准混凝土大为缩短．本文分析了产生这一现象的原因，认为在诸多影响因素中，天然火山灰的结构属性对此所起的作用不容忽视；同时，提出可采用适宜的控制手段，延缓天然火山灰碾压混凝土拌合物的初凝时间，并使该混凝土的各项性能满足设计和施工要求．

| Abstract: | The setting-time of the RCC blended with natural pozzolana(I,e.pozzolanic RCC)is shortet that the controlled Rcc(i.e.without pozzoalna )the reasons of the phenomenon have been alalyzed in this paper.The affection of matural pogolana's natural lproperties on setting-timecan not be inored,though the effectual factros anr more.Furthermore,it is possible to retard the setting-time of pozzolanis PCC by suitalb control metohd,and let the poperties of such concrets meet the demands of desin and corstrrueion. |
