工业废渣代替粘土生产普通硅酸盐水泥的研究

Study on the Ordinary Portland Cement by Using the Industrial Waste Slags to Replace Clay

叙述了利用工业废渣煤矸石、磷渣、锰渣、磷石膏、液态渣代替粘土生产普通硅酸盐水泥的试验。结果表明水泥中工业废渣的掺量超过 5 0 % ,其 3d抗压强度达 32 .1MPa,2 8d抗压强度达5 8.6 MPa。用此种工艺可生产 5 2 5 R早强水泥。

Producing the ordinary Portland cement by using the industrial waste slags,gangue,phosphate slag,manganese slag,phosphogypsum and liguid slag to replace claycompletely was studied.Although the industrial waste slag content in the ordinary Portland cement is over 50%,its compressive strengths for 3d and 28d are 32.1MPa and 58.6MPa respectively.Therefore,the authors concluded that the early strength cement of 525R can be produced by the process described in this paper.
