Cement clinker fired by mixing high-magnesium low-grade limestone and solid waste as well as method and application of cement clinker
The invention discloses cement clinker fired by mixing high-magnesium low-grade limestone and solid waste, and a method and application thereof. The cement clinker is composed of a component X and a component Y, the component X comprises the following components in percentage by mass of oxides: 35%-50% of CaO, 6%-22% of SiO2, 20%-35% of Al2O3, 3%-13% of Fe2O3, 3%-10% of MgO and 2%-6% of SO3; the component Y is B2O3 accounting for 0.1-3% of the total mass of the component X; the cement clinker comprises the following raw materials: high-magnesium low-grade limestone, aluminum solid waste, iron solid waste, magnesium solid waste, sulfur solid waste and a clinker synergistic sintering agent. According to the invention, the low-grade limestone and the solid waste are mixed and fired to prepare the low-calcium high-performance cement clinker with rapid development of early strength and sustainable development of middle and later periods, and the comprehensive utilization rate is improved.
本发明公开一种高镁低品位石灰石和固废混合烧成水泥熟料及方法和应用，水泥熟料由组分X和组分Y组成；以氧化物的质量百分比计，组分X包括以下组分：CaO含量为35％～50％，SiO2含量为6％～22％，Al2O3含量为20％～35％，Fe2O3含量为3％～13％，MgO含量为3％～10％，SO3含量为2～6％；组分Y为占组分X总质量0.1～3％的B2O3；水泥熟料的原料包括高镁低品位石灰石、铝质固废、铁质固废、镁质固废、硫质固废和熟料协同烧成剂。本发明将低品位石灰石和固废混合烧成，制备出了具有早期强度发展迅速，中后期持续发展的低钙高性能水泥熟料，提高综合利用率。
