磁选尾渣混凝土路面砖的试验研究

Experimental research on the pavement bricks of the concrete with magnetic separation tail slag

应用正交试验设计法，对利用磁选尾渣（经磁选后的平炉钢渣）作集料的砼路面砖的配合比进行优化，找出了较佳配合比及工艺条件．结果表明；低碱度、低活性的尾渣可以取代砂石作为集料应用于砼制品中，并改善了制品的物理力学性能．

Based on the cross experiment design method the authers optimaze the mix proportion and the technigue condition of the paving brick of the concrete with magnetic separation tail slag. The experiment results show the tail slag of low -alkalinity and low -activity may be used in concrete products to substitute sand and crushed stone and improve the physical property of products.
