| 摘 要： | 通过对尾矿砂石混凝土施工性能的系统试验研究,探讨了用尾矿砂石代替天然砂石后,对混凝土施工性能的影响.研究分析表明,在用水量相同、水灰比相同、外加剂用量基本相同的情况下,尾矿砂石混凝土的坍落度小于天然砂混凝土;配合比相同、坍落度相近时,尾砂石混凝土与天然砂石混凝土泵送性能相差无几;相同配合比时,铁尾矿砂石混凝土的黏聚性和保水性略差于天然砂石混凝土.

| Abstract: | Based on the systematic experimental research on the construction performance of the tailing dinax concrete,the influence on the concrete construction performance is explored through using tailing dinax instead of the natural dinax.The research shows that on the condition of the same water volume,same water-lime proportion,same additive,the slump of the tailing dinax concrete is lower than that of the natural dinax.Under the condition of the same proportion,same slump,there is no significant difference on t... |
