Air-hardening inorganic cementing material and preparation method thereof
The invention provides an air-hardening inorganic cementing material and a preparation method thereof. The preparation method comprises: drying, crushing, and grounding raw materials containing serpentine minerals, and obtaining first powder; carrying out drying, crushing and grinding treatment on the carbonate-containing minerals to obtain second powder; mixing the first powder and the second powder according to a predetermined mass ratio, heating and calcining to obtain third powder with active magnesium silicate as a main component; and grinding the third powder to obtain the air-hardening inorganic cementing material. The air-hardening inorganic cementing material is prepared by adopting the preparation method. The air-hardening inorganic cementing material obtained by the invention has the advantages of low porosity, high compressive strength, high water resistance, good fireproof performance, good temperature resistance and the like after being hardened, and has important application in the building material industry.
本发明提供了一种气硬性无机胶凝材料及其制备方法，所述制备方法包括：将含有蛇纹石矿物的原料进行干燥、破碎和粉磨处理，获得第一粉体；将含有碳酸盐的矿物进行干燥、破碎和粉磨处理，获得第二粉体；按预定质量比混合第一粉体和第二粉体，并加热煅烧，获得以活性硅酸镁为主要成分的第三粉体；将第三粉体粉磨处理后，获得气硬性无机胶凝材料。气硬性无机胶凝材料采用上述制备方法制备获得。本发明获得的气硬性无机胶凝材料硬化后具有孔隙率低、抗压强度大、耐水性强、防火性能好、耐温性能好等优点，在建筑材料工业中具有重要的用途。
