摘要
根据钼尾矿粉的细度条件,选择与0.63mm以上粒径砂混合,提出了利用钼尾矿粉替代砂生产混凝土小型空心砌块较为合理的替代量。通过正交试验方法进行钼尾矿粉混凝土小型空心砌块母体混凝土的优化配合比设计,研制钼尾矿粉混凝土小型空心砌块。
Based on the fitness conditions, molybdenum tailings powder is selected as substitute to mix with sands with the particle size of above 0.63mm in the production of hollow bricks and the reasonable proportion of the substitute is proposed for the concrete. The orthogonal test is applied to optimize molybdenum tailings concrete mixing design in the production of small concrete bricks as well.
