| 摘 要： | 为确保三峡水利枢纽工程安全运行,从50年代起就开始研究混凝土碱骨料反应问题。试验查明,工程混凝土所用的花岗岩骨料属于非活性骨料;在天然砂石料中含有的燧石、流纹岩、凝灰岩等具有碱活性反应;白云质灰岩和灰质白云岩尚待进一步试验论证。

| Abstract: | The scale of the Three Gorges Project is grandiose, and it has tremendous comprehensive benefit. In order to ensure a long-time reliability and safe operation of the project, since the 50s' we have investigated the problems of AAR in concrete for the project.Through tests we have made clear that the granite is non-active aggregate, and the chert, quartz trachyte, tufa in gravel have AAR. further work should be done to ascertain whether there is AAR in the dolomitic limestone and lime dolostone. |
