摘要
钠系防冻剂对白云石、石灰石等粗骨料的碱—骨料反应表明:它们有加速白云石的去白云石化作用,工程中不宜使用,但对石灰石影响不大,工程中可以选用。
The effects of the antifreezing admixture Containing sodium on extension property of aggregates of dolomite and limestone were investigated. Retults were shown that de-dolomitization of dolomite was speeded up, and it is not sutable to use dolomite in any engineering but its effect on limestone almost was neglected and it is suitable to use.
