目前碱-集料反应分成三类,即碱-硅酸反应,碱-硅酸盐反应和碱-碳酸盐反应。分类不仅具有学科意义,同时与寻找鉴定集料的新方法和防止措施均密切相关。本文综述了分类形成的历史过程,各类反应的主要特徵、反应机理及其相应的鉴定方法和抑制措施。根据近年来的研究结果,文中提出,碱虽然会与某些页硅酸盐反应,但未证实会导至膨胀。因而认为没有必要分出单独一类碱-硅酸盐反应,而建议分成碱-硅酸反应和碱-碳酸盐反应两类。
At present, the alkali-aggregate reaction is divided into three categories, namely alkali-silicic acid reaction, alkali-silicate reaction and alkali-carbonate reaction. Classification is not only of academic significance, but also closely related to finding new methods and preventive measures for the identification of aggregates. This article summarizes the historical process of classification, the main characteristics of various types of reactions, reaction mechanism and its corresponding identification methods and inhibition measures. According to the results of recent studies, it is suggested that although the base will react with some phyllosilicates, it has not been confirmed that it will cause swelling. Therefore, it is considered unnecessary to separate a single type of alkali-silicate reaction, and it is proposed to classify them into alkali-silicic acid and alkali-carbonate reactions.
