碱 集料反应能导致混凝土的严重破坏 ,应严格限制混凝土外加剂中碱含量。碱 集料反应 (ＡＡＲ)是混凝土内部碱与集料中某些组分之间的反应 ,可将其分为碱 硅酸反应(ＡＳＲ)和碱 碳酸盐反应 (ＡＣＲ)。参与反应的碱可以是水泥、混合材、化学外加剂和水中的碱 ,也可以是从环境 Alkali aggregate reaction can lead to serious damage to concrete, concrete additives should be strictly limited to the alkali content. The alkali aggregate reaction (AAR) is the reaction between the internal alkali of concrete and some components in the aggregate, which can be divided into alkali silicic acid reaction (ASR) and alkali carbonate reaction (ACR). The base involved in the reaction may be cement, a mixture, a chemical admixture and a base in water, or it may be from the environment
