Composite auxiliary cementing material as well as preparation method and application thereof
The invention discloses a composite auxiliary cementing material as well as a preparation method and application thereof. The composite auxiliary cementing material mainly comprises microorganism synergistic carbon sequestration waste residue powder and an aluminum-containing auxiliary cementing material. The preparation method comprises the following steps: testing the contents of aluminum oxide and calcium carbonate in the microorganism synergistic carbon sequestration waste residue powder and the aluminum-containing auxiliary cementing material, so that the mass ratio of the aluminum oxide to the calcium carbonate is 0.5-3.0 when the microorganism synergistic carbon sequestration waste residue powder is compounded with one or more aluminum-containing auxiliary cementing materials. The prepared composite auxiliary cementing material is higher in overall chemical matching performance and higher in hydration activity when being used for cement concrete, the clinker coefficient is reduced, carbon emission is reduced, and the microorganism synergistic carbon sequestration waste residue powder is a negative carbon material.
本发明公开了一种复合辅助胶凝材料及其制备方法和应用，所述复合辅助胶凝材料主要包括微生物协同固碳废渣粉和含铝辅助胶凝材料。所述制备步骤包括测试微生物协同固碳废渣粉和含铝辅助胶凝材料中氧化铝和碳酸钙含量，使得微生物协同固碳废渣粉和一种或多种含铝辅助胶凝材料复合时，氧化铝和碳酸钙的质量比为0.5～3.0。制备的复合辅助胶凝材料整体化学匹配性更强，用于水泥混凝土时水化活性更高，有助于降低熟料系数，减少碳排放，且微生物协同固碳废渣粉本身即为负碳材料。
