Preparation method and application of ultrahigh-activity solid waste-based carbon sequestration auxiliary cementing material
The invention provides a preparation method and application of an ultrahigh-activity solid waste-based carbon sequestration auxiliary cementing material, and belongs to the technical field of building materials. The method comprises the following steps: (1) pre-grinding the medium-low-activity high-aluminum pozzolanic solid waste to a corresponding particle size range to obtain medium-low-activity high-aluminum pozzolanic solid waste pre-ground micro powder, and adding a corresponding composite chemical additive in the pre-grinding process; and (2) mixing the carbon sequestration solid waste, the medium and low activity high-aluminum pozzolanic solid waste pre-ground micro powder and the calcium-increasing component according to a specific mass ratio, and carrying out ultrafine grinding to a corresponding particle size range to obtain the ultrahigh activity solid waste-based carbon sequestration auxiliary cementing material. According to the ultrahigh-activity solid waste-based carbon sequestration auxiliary cementing material prepared by the method disclosed by the invention, the activity index of 30% of the cementing material can reach S130-S145 level, and the activity index of 50% of the cementing material can reach S120-S130 level.
本发明提供了超高活性固废基固碳辅助性胶凝材料的制备方法及其应用，属于建筑材料技术领域。该方法包括：(1)将中低活性高铝火山灰质固体废弃物预粉磨至相应粒径范围，以得到中低活性高铝火山灰质固体废弃物预粉磨微粉，预粉磨过程中加入相应复合化学助剂；(2)将固碳固体废弃物与中低活性高铝火山灰质固体废弃物预粉磨微粉、增钙组分三者以特定质量比配料并超细粉磨至相应粒径范围即得到超高活性固废基固碳辅助性胶凝材料。通过本发明方法制得的超高活性固废基固碳辅助性胶凝材料，30％掺量活性指数高达S130‑S145级，50％掺量活性指数可达S120‑S130级。
