| 摘 要： | 将增钙液态渣、矿渣分别磨细，与激发剂混合后制成生态型胶凝材料。激发剂由改性脱硫石膏和低碱度材料组成。选择增钙液态渣何渣质量比、激发剂用量和粉磨细度3个因素，采用正交试验L9（34）进行配方和工艺参数优化。按GB／T1 7671—1999对胶凝材料进行测试，28d胶砂抗压强度达到34MPa,抗折强度达到5．9MPa。安定性、凝结时间合格。对该胶凝材料在蒸养尾矿砖上的应用情况进行了测试，产品性能与32．5等级的普通硅酸盐水泥相当。

| Abstract: | An ecotype binder is prepared after calcium enriched cyclone-furnace slag(CECFS) and granulated blast-furnace slag(GBFS) were ground respectively and then mixed with an activator.The activator is composed of modified desulphurization gypsum and weak alkaline materials.Three factors, ratio of CECFS/GBFS ratio,the amount of activator and grinding fineness,are selected for experiment design.Orthogonal experiment L9(34)was used to optimize formulation and process parameters.The 28d compressive mortar strength,determined according to GB/T17671-1999 standard,is up to 34 MPa and bending strength 5.9 MPa.Stability and setting time are qualified.The application of this binder in steam-cured tailings brick is tested,and the test results show that property of this binder is equivalent to Portland cement with Grade(32.5.) |
