Iron aluminate cement clinker, solid-waste-based high-strength iron aluminate cement and preparation methods of iron aluminate cement clinker and solid-waste-based high-strength iron aluminate cement
The invention discloses an aluminoferrite cement clinker, solid-waste-based high-strength aluminoferrite cement and a preparation method of the aluminoferrite cement clinker and the solid-waste-based high-strength aluminoferrite cement. The method comprises the following steps: calcining and quenching modified phosphogypsum, limestone, tungsten tailings, lepidolite smelting slag and other solid waste raw materials to obtain an aluminoferrite cement clinker, and mixing the aluminoferrite cement clinker with desulfurized gypsum, fly ash and a cement additive to obtain the solid waste-based high-strength aluminoferrite cement. The aluminoferrite cement takes various mine beneficiation and smelting solid wastes as main raw materials, greatly reduces the cost, has the characteristics of high early strength, high construction speed, chloride ion resistance, good sulfate erosion resistance and the like, can be widely applied to rapid construction and repair engineering of ocean engineering or various concrete buildings, realizes efficient recycling of the solid wastes, and has a good application prospect. The method has potential application value and remarkable economic and social benefits.
本发明公开了一种铁铝酸盐水泥熟料、固废基高强铁铝酸盐水泥及制备方法。将改性磷石膏与石灰石、选钨尾矿和锂云母冶炼渣等固废原料经过煅烧和急冷处理，即得铁铝酸盐水泥熟料，所述铁铝酸盐水泥熟料与脱硫石膏、粉煤灰和水泥外加剂混合即得固废基高强铁铝酸盐水泥，该铁铝酸盐水泥以多种矿山选冶固废为主要原料，大大降低了成本，且具有早起强度高，施工速度快，耐氯离子、硫酸盐侵蚀能力好等特点，可广泛应用于海洋工程或多种混凝土建筑的快速施工与修复工程，实现了固废的高效循环利用，具有潜在的应用价值，经济效益和社会效益显著。
