摘要
较系统地研究了三种锂盐对沸石化珍珠岩集料砂浆ASR膨胀的影响 ,证实了锂盐抑制效果的长期有效性 ,确立了不同碱含量条件下锂盐有效抑制ASR膨胀的Li与Na的摩尔比 ,并从机理上加以探讨 .
Effect of three kinds of lithium compounds on ASR expansion of zeolitization perlite-cement mortars was systematically investigated. The long_term effectiveness of lithium compounds on inhibiting ASR expansion was tested, and the relationship between molar rate of n(Li)/n(Na) and the alkali contents in systems was established. The govening mechanism of such effects was also discussed briefly.
