摘要
试验首先研究了铁尾矿的组成和性能,通过外加掺合物和改变粒径级配方式对其改善,并测试其力学性能。结果表明:掺入高效减水剂可以改善和易性,添加氧化钙可以增加强度,铁尾矿按照最大级配理论进行组合也可提高强度。
The paper investigates the composition and performance of the iron tailing, then improves the properties by neans of adding minerals and changing diameter grade design, finally tests the mechanical properties. As a result, the high reducer can improve the the the peaeeability, the concrete strength will be increased by adding calcium oxide, furthermore, also by designing the combination ia ac- cordance with the maximum gradation theory.
