摘 要:河砂的堿活性對工程結構的破壞能力至今雖然還沒有定論,但其影響是不容忽視的。本文對廣東的幾個主要砂源(西江、東江、北江)的河砂進行了堿活性檢驗,發現西江河砂潛在和明顯堿硅酸活性的存在幾率相當高,東江河砂亦發現有潛在活性的樣品,北江河砂經初步分析還不能判定是否有潛在堿—硅酸反應危害。
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.
