Magnesium silicate cementing material as well as preparation method and application thereof
The invention provides a magnesium silicate cementing material and a preparation method and application thereof.The preparation method comprises the steps that mixing raw materials containing serpentine minerals and first auxiliary materials according to a first preset mass ratio, obtaining a first powder particle body after pretreatment, wherein the first auxiliary materials are at least one of carbonate minerals and carbonate mineral tailings, the first preset mass ratio comprises the condition that the amount of the first auxiliary material is 0; calcining the first powder particle body to obtain a second powder particle body of which the main crystal phase is olivine; mixing the second powder particle body and a second auxiliary material according to a second preset mass ratio, so that the magnesium silicate cementing material is obtained after grinding, wherein the second auxiliary material is at least one of lime, carbonate cement clinker, carbide slag, gypsum and water glass powder; the second preset mass ratio comprises the condition that the amount of the second auxiliary material is 0. The magnesium silicate cementing material powder has gelling property after being mixed with water, a formed body is cured into a stone-like body after being cured, and the stone-like body is high in strength, good in stability, free of expansion after absorbing water, free of frost returning and high in durability.
本发明提供了一种硅酸镁胶凝材料及其制备方法和应用，所述制备方法包括：按第一预定质量比混合含有蛇纹石矿物的原料与第一辅料，经预处理后获得第一粉粒体，第一辅料为碳酸盐矿物和碳酸盐矿物尾渣中的至少一种；第一预定质量比包括第一辅料量为0的情况；煅烧第一粉粒体，获得主晶相为橄榄石的第二粉粒体；按第二预定质量比混合第二粉粒体和第二辅料，粉磨后获得硅酸镁胶凝材料，第二辅料为石灰、碳酸盐水泥熟料、电石渣、石膏和水玻璃粉体中的至少一种；第二预定质量比包括第二辅料量为0的情况。本发明的硅酸镁胶凝材料粉体加水拌和后具胶凝性，成型体经养护后固化为石状体，石状体的强度高，安定性好，吸水后不膨胀，不返霜，耐久性强。
