膨胀剂在大体积混凝土和薄壁混凝土中的应用

The Application of Expansion Agent in Mass Concrete and Thin Wall Concrete of Wu Jiang Municipal Century Mansion

本文介绍了UEA膨胀剂和JM 2型高效减水剂在大体积混凝土和超长、超高薄壁混凝土中的应用情况 ,测定了掺UEA和JM 2的大体积混凝土的温度 时间曲线 ,指出了上述混凝土防裂机理 ,对同类混凝土工程具有一定的借鉴和参考价值。

The application of UEA expansion agent and JM-2 concrete superplasticizer in mass concrete and superlong superhigh thin wall concrete are described in this paper.The curve of temperature-time in mass concrete admixed with UEA & JM-2 is described.The author points out the resisting crack principle about the preceding concrete.It will be of use value for reference to the similar concrete engineering.
