摘要
以适量硅灰与P.O 42.5水泥复合组成的胶材,与锰渣经过拌合、成型、养护等工序后,制得锰渣轻质保温墙砖。通过强度、导热系数的回归分析,探讨了锰渣墙砖的干缩机理;通过XRD与SEM分析,对比了新旧方案下锰渣复合材料的早期水化产物与微观结构。
The manganese slag lightweight insulation wall bricks are prepared through manganese slag and cementitious materials with silica fume and P. O 42.5 cement after mixing, molding and curing. Through the strength and thermal conductivity regression analysis, the drying shrinkage mechanism of the manganese slag wall bricks is discussed. And the hydration products at early age and mierostructure of the manganese slag compound material are compared by XRD and SEM under the new and old schemes.
