| 中文摘要: |
| 针对湖南青峰煤矿#1和#2堆场的自燃煤渣化学成分和活性分析，将自燃煤渣按一定比例替代燃煤炉渣作生料配料烧制熟料，和将#1堆场自燃煤渣替代部分混合材生产水泥。结果表明，利用#1和#2堆场的自燃煤渣均能生产出优质硅酸盐熟料，利用#1堆场自燃煤渣生产的水泥，各项指标均达到GB/T 21372—2008硅酸盐水泥熟料标准，且社会、经济效益显著。 |
| 英文摘要: |
| In view of analysing chemical compositionand activity of spontaneous combustion coal slag in #1 and #2 yard of Hunan qingfeng mine, using spontaneous combustion coal slag to replace fuel coal slag by certain proportion as raw ingredients sinters cement clinker and using spontaneous combustion coal slag of #1 yard to replace part of mixed material produces cement.Result shows that using spontaneous combustion coal slag of #1 and #2 yard can both produce high-quality Portland clinker.Especially production in #1 yard，the indicators have reached standard of Portland cement clinker GB/T 21372—2008 ,which has remarkable social and economic benefit. |
