碱集料反应的介电谱特性

Characteristics of Dielectric Spectroscopy of Alkali Aggregate Reaction

摘要:

对碱集料反应的介电谱特性进行的讨论结果表明，如果有碱集料反应，其Cole-Cole图中存在1条起自原点的垂直线，且集料的碱活性越强，该垂直线越长，矿物掺合料可抑制碱集料反应。

Abstract:

The characteristics of dielectric spectroscopy of alkali aggregate reaction is discussed. It is shown that a perpendicular line from the origin of Cole Cole plot appears if there exists alkali aggregate reaction in concrete. The higher the alkali reactivity is, the longer the line will be. It is also shown that by adding mineral admixture the alkali aggregate reaction will be inhibited.
