Quick-setting filling cementing material with high fluidity under low-temperature condition
The invention discloses a quick-setting filling cementing material with high fluidity under a low-temperature condition, and particularly relates to the field of material science and engineering, and the quick-setting filling cementing material comprises the following raw materials in parts by weight: 50-80 parts of blast furnace slag powder; 8-15 parts of cement clinker; 2-6 parts of an alumina clinker master batch; 3-20 parts of ground steel slag powder; 2-30 parts of gypsum; and 0.2-0.5 part of powder water reducing agent. The blast furnace slag powder is powder formed by grinding blast furnace slag through a ball mill, the specific surface area of the blast furnace slag powder is 400-520 m < 2 >/kg, the cement clinker is powder formed by grinding clay or other raw materials in the Portland cement industry, mixing, calcining at high temperature and then grinding, and the specific surface area is 300-350 m < 2 >/kg. The special cementing material for mine filling is a uniformly mixed finished product, and has the advantages of short cementing time, fast early strength increase, slow later strength increase, good flowability and pumpability, no toxicity, harmlessness, capability of meeting mine filling requirements, simple production process, no pollution and high cost performance.
本发明公开了一种低温条件高流动性快凝充填胶凝材料，具体涉及材料科学与工程领域，包括以下重量份的原料：50～80份的高炉矿渣粉；8～15份的水泥熟料；2～6份铝氧熟料母料；3～20份磨细钢渣粉；2～30份的石膏；0.2～0.5份粉体减水剂，所述高炉矿渣粉为高炉矿渣通过球磨机粉磨而成的粉体，且所述高炉矿渣粉的比表面积为400～520㎡/kg，所述水泥熟料为硅酸盐水泥工业中黏土或其他原料经粉磨混合后高温煅烧再粉磨成的粉体，比表面积为300～350㎡/kg。本发明提供一种混合均匀的成品，具备胶凝时间短、早期强度增长快、后期强度缓慢增长，流动性和泵送性好，无毒无害，能够满足矿井充填要求，生产工艺简单无污染，性价比高的矿山充填专用胶凝材料。
