Magnesium silicate composite cementing material and preparation method thereof
The invention provides a magnesium silicate composite cementing material and a preparation method thereof. The preparation method comprises the following steps: drying, crushing and crushing raw materials containing serpentine minerals to obtain powder containing the serpentine minerals; calcining the powder containing the serpentine minerals to obtain active magnesium silicate powder; and matching the active magnesium silicate powder with an auxiliary agent to obtain the magnesium silicate composite gel material. The magnesium silicate composite cementing material comprises the product prepared according to the method. According to the invention, the use amount of cement can be reduced, carbon emission and environmental pollution can be reduced, resource utilization of the serpentine mineral-containing solid waste is realized, and the source and range of the cementing material are expanded.
本发明提供了一种硅酸镁复合胶凝材料及其制备方法。所述制备方法可包括以下步骤：将含有蛇纹石矿物的原料进行干燥、破碎和粉碎处理，获得含有蛇纹石矿物的粉体；将含有蛇纹石矿物的粉体进行煅烧处理，获活性硅酸镁粉体；将活性硅酸镁粉体与助剂配合，得到硅酸镁复合凝胶材料。所述硅酸镁复合胶凝材料包括按照上述方法制备出的产品。本发明可降低水泥用量，有助于减少碳排量和环境污染，实现含蛇纹石矿物固废的资源化利用，拓展了胶凝材料的来源和范围。
