超细铅锌尾矿砂混凝土的研究

Research on the Making of Concrete with Super—fine Tail Mine Sand of Lead and Zinc

本文是关于如何利用工业废料—铅锌尾矿砂,制造混凝土和空心建筑砌块。该砂的细度模数 M 为0.4。如此的超细砂铅混凝土的生产工艺带来了很多困难。通过大量试验得出了超细砂的配合比。同时应用造壳理论我们还获得了超细砂混凝土的生产工艺。

This paper deals with the making of concrete and hollow building blocks with tail myne sand of lead and zinc,a kind of industrial garbage.The fineness modulusM is 0. 4,which causes difficulties in concrete production.Mix ratio of super—minute sand is obtained through many experiments and the making procedure of super—minuitesand concrete is obtained by means of the theory of making shells.
