Ecological cementing material and preparation method thereof
The invention discloses an ecological cementing material and a preparation method thereof, and relates to the technical field of building materials, and the ecological cementing material is prepared from the following raw materials in parts by mass: 5-20 parts of red mud, 5-25 parts of gypsum, 30-50 parts of slag powder and 30-50 parts of fly ash. The raw materials comprise red mud, industrial byproduct gypsum and other silicon-aluminum industrial solid wastes (such as fly ash and slag), the raw materials are ground to a certain fineness and then uniformly mixed, water is added for stirring, forming and standard curing are performed, and the ecological cementing material is prepared. The coupling excitation effect of the red mud and the industrial byproduct gypsum is fully exerted, so that the gelling activity of the ecological gelling material is improved, hydration products are connected more tightly, and the overall structure of the gelling material is compact. The 28-day compressive strength can reach 50 MPa or above, and the characteristic of reasonable strength is achieved.
本发明公开了一种生态胶凝材料及其制备方法，涉及建筑材料技术领域，生态胶凝材料原料按照质量分数计，包括以下组分：赤泥5～20份、石膏5～25份、矿渣粉30～50份以及粉煤灰30～50份。本发明原料包括赤泥、工业副产石膏、其他硅铝质工业固体废弃物(如粉煤灰、矿渣等)，将原料粉磨至一定细度后混合均匀、加水拌和、成型、标准养护，完成生态胶凝材料的制备。通过充分发挥赤泥与工业副产石膏的耦合激发作用，提高该生态胶凝材料的胶凝活性，使其水化产物之间连结更加紧密，从而使得胶凝材料的整体结构致密。其28天抗压强度可达50MPa以上，具有强度合理的特性。
