镁渣作水泥混合材的研究

The study of using magnesium slag as cement admixture

从活性、易磨性和水泥的物理性能等方面进行了炼铁工业废渣—镁渣作水泥混合材的可行性研究，结果表明，试验所用镁渣是一种活性、易磨性均高于矿渣的活性混合材；采用#25硅酸盐水泥熟料，控制水泥中MgO在6％以下时，掺30％镁渣作水泥混合材能够生产出安定性合格的#422水泥。

The feasibility study of using magnesium melting slag as cement admixture is carride out from the activity, grindability and physial performance etc. The result shows the magnesium slag usde for test is a kind of active admixture, of which, activity and grindability are higher than those of furnace slag; # 425 cement with qualified stability can be produced by using # 525 Portland cement clinker with the content of MgO in the cement to be controlled under 6% and the amount of the slag within 30%.
