Low-heat Portland cement clinker with early strength characteristic and preparation method thereof
The invention discloses a low-heat Portland cement clinker with an early strength characteristic and a preparation method thereof. The cement clinker comprises the following raw materials in percentage by mass: 60-85% of a calcium raw material; 2 to 20 wt.% of a siliceous raw material; 1-10 wt.% of an aluminum raw material; 1-10 wt.% of an iron correction raw material; 0.1 to 5 wt.% of a mineralizing agent; the mineralizer is at least one of fluorgypsum, phosphogypsum, fluorine slag, manganese slag, yellow phosphorus slag, copper slag and zinc slag. According to the invention, a special process is adopted to control the mineral phase transformation in the clinker sintering process, so that the sizes and structures of C3S and C2S in the low-heat Portland cement are changed, the early strength of the cement is improved, the characteristic of low hydration heat is maintained, the internal temperature rise of the concrete is reduced, temperature cracks are prevented, and the overall quality and safety of a project are improved.
本发明公开了一种具有早强特性的低热硅酸盐水泥熟料及其制备方法，所述水泥熟料包括以下质量百分比计的原料：钙质原料：60～85wt.％；硅质原料：2～20wt.％；铝质原料：1～10wt.％；铁质校正原料：1～10wt.％；矿化剂：0.1～5wt.％；所述矿化剂为氟石膏、磷石膏、氟渣、锰渣、黄磷渣、铜矿渣、锌渣中的至少一种。本发明采用特殊工艺控制熟料烧成过程中的矿物相转变，改变了低热硅酸盐水泥中C3S和C2S的尺寸与结构，提高水泥的早期强度的同时，又保持了低水化热的特性，降低混凝土内部温升，预防温度裂缝，提高工程的整体质量与安全性。
