| Abstract: | 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. |

| Keywords: | Antifreezing admixture containing sodium dolomite limestone alkali-acarbonate reaction |
