Low-heat Portland cement clinker based on aerated concrete waste and preparation method thereof
The invention relates to the technical field of preparation of special cement clinker, in particular to low-heat Portland cement clinker based on aerated concrete waste and a preparation method of the low-heat Portland cement clinker, and the low-heat Portland cement clinker comprises the following raw materials in percentage by weight: 60-80% of limestone, 5-25% of aerated concrete waste, 2-10% of clay, 1-10% of nonferrous metal ash and 0.1-3% of mineralizer. By adding the mineralizer, the crystal lattice of reactants in the cement raw material is destroyed, the chemical activity of the crystal lattice is improved, and the solid-phase reaction of the cement raw material is accelerated, so that the burnability of the cement raw material is improved, the firing temperature and heat consumption are reduced, and the quality of the clinker is improved.
本发明涉及特种水泥熟料制备技术领域,具体涉及基于加气混凝土废料的低热硅酸盐水泥熟料及其制备方法,所述低热硅酸盐水泥熟料包括按重量百分比计的以下原料:60~80wt.%石灰石、5~25wt.%加气混凝土废料、2~10wt.%粘土、1~10wt.%有色金属灰渣和0.1~3wt.%矿化剂。本发明通过加入矿化剂,破坏水泥生料中反应物的结晶格子,提高结晶格子的化学活性,加速其固相反应,从而改善其易烧性、降低烧成温度和热耗、提高熟料的质量。
