| 摘 要： | 河砂的碱活性对工程结构的破坏能力至今虽然还没有定论,但其影响是不容忽视的。本文对广东的几个主要砂源(西江、东江、北江)的河砂进行了碱活性检验,发现西江河砂潜在和明显碱硅酸活性的存在几率相当高,东江河砂亦发现有潜在活性的样品,北江河砂经初步分析还不能判定是否有潜在碱—硅酸反应危害。

| Abstract: | The examination for alkali activity of some types of sand,which are from west River,East River and North River of Guangdong Province,has been down.And the rezults show that,in West River there is a very high probability of existing the alkali activity of sand,and some samples from East River appear to have potential alkali activity,but North River sand can't finally be judged whether it has potential alkali activity or not. |
