摘要
碱集料反应是影响混凝土耐久性的重要方面。本文利用交流阻抗方法 ,通过对三种不同陶粒混凝土碱集料反应的分析与讨论 ,认为陶粒具有不同程度的碱活性 ,但由于其自身多孔结构的特点 。
? The durability of concrete is influenced by alkali aggregate reaction(AAR).AC impedance technique was applied to study AAR of Concrete with three different lightweight aggregate(LWA).Though there is alkali reactivity of LWA,there wasn't expansion in lightweight concrete because of the pore structure in lightweight aggregate. 〔
