Low-carbon low-heat high-belite cement clinker based on waste concrete and preparation method of low-carbon low-heat high-belite cement clinker
The invention discloses a low-carbon low-heat high belite cement clinker based on waste concrete and a preparation method of the low-carbon low-heat high belite cement clinker, limestone, coal gangue, waste concrete and iron raw materials are used as raw materials, the raw materials are calcined to generate the high belite cement clinker, and the belite content in the clinker is 55-70wt%. The high belite cement uses the waste concrete as the raw material, so that the cost is saved, the use of limestone, sandstone and other raw materials is reduced, the resource utilization rate is increased, and the waste concrete is reasonably treated, recycled and resourcefully utilized. The high belite cement clinker disclosed by the invention is good in burnability, the calcination temperature is 1300-1400 DEG C, and the high belite cement clinker has remarkable energy-saving and emission-reducing effects due to relatively low decomposition and calcination temperatures, the coal consumption and carbon emission of the clinker are reduced in the production process, and the production cost of the clinker is reduced.
本发明公开了一种基于废弃混凝土的低碳低热高贝利特水泥熟料及其制备方法，以石灰石、煤矸石、废弃混凝土、铁质原料为生料，煅烧生成高贝利特水泥熟料，熟料中贝利特含量在55～70wt.％。本发明所涉及的高贝利特水泥使用废弃混凝土作为原材料，不仅节约了成本，减少了石灰石，砂岩等原材料的使用，同时也提高了资源利用率，废弃混凝土的合理处置、回收及资源化利用。本发明所涉及的高贝利特水泥熟料易烧性好，煅烧温度为1300℃～1400℃，较低的分解、煅烧温度使得其具有显著的节能减排效果，且生产过程中降低了熟料的煤耗以及碳排放，减少了熟料的生产成本。
