Early-strength low-hydration-heat Portland cement clinker prepared from rare earth tailings and preparation method thereof
The invention discloses an early-strength low-hydration-heat Portland cement clinker prepared from rare earth tailings and a preparation method thereof, belongs to the field of cement clinker manufacturing, and solves the problem of contradiction between low hydration heat and early strength of cement clinker in the prior art. The invention discloses an early-strength low-hydration-heat Portland cement clinker prepared from rare earth tailings, the early-strength low-hydration-heat Portland cement clinker is prepared by calcining a raw material, and the raw material is prepared from the following raw materials in percentage by mass: 78-80% of limestone, 10-12% of sandstone, 3-6.5% of aluminum ore waste rock and 2-3% of copper ore tailings; and 0.5%-3% of rare earth tailings. The method is scientific in design and ingenious in conception, the rare earth tailings are efficiently utilized as the clinker firing mineralizer and the low-hydration heat clinker mineral activating agent with high quality, and the problems that the low-heat Portland cement clinker is low in early strength and slow in strength development are solved.
本发明公开了稀土尾矿制备的早强低水化热硅酸盐水泥熟料及制备方法，属于水泥熟料制造领域，解决现有技术中水泥熟料低水化热和早强矛盾的问题。本发明公开的稀土尾矿制备的早强低水化热硅酸盐水泥熟料，所述早强低水化热硅酸盐水泥熟料由生料煅烧制成，其中，生料由包括以下质量百分比的原料制成：石灰石78％～80％，砂岩10％～12％，铝矿废石3％～6.5％，铜矿尾渣2％～3％；稀土尾矿0.5％～3％。本发明设计科学，构思巧妙，高质高效利用稀土尾矿为熟料烧成矿化剂和低水化热熟料矿物活化剂，解决了低热硅酸盐水泥熟料早期强度低、强度发展慢难题。
