摘要
用锰铁高炉产出的原状废渣代替部分水泥制作的砂浆试件,强度下降幅度较大。对锰渣(水淬后)和烟道灰的活性进行物理激发试验,结果表明采取机械球磨的方式可使锰渣和烟气灰的活性得到激发。球磨时间愈长,废渣愈细,表现出的活性也愈大。物理激发对锰渣的作用效果更明显;烟气灰能使水泥砂浆的密实性提高,对水泥砂浆的早期强度有利。
Original state waste residue from Fe-Mn blast furnace substituting for part cement is made into mortar specimens and the mortar strengths drop largely. Physical method can activate the activity of the waste residue. The longer the grinding time is, the thinner and more active the waste residue is. Physical activation effect is better for manganese slag than for off ash gas. But off ash gas can make the mortar more compaction and be propitious to the early strength of mortar.
