Construction waste micro-powder carbonization and reactivation method
The invention discloses a construction waste micro-powder carbonization and reactivation method, and belongs to the technical field of construction materials. The construction waste micro-powder carbonization and reactivation method comprises the following steps: mixing 20-25 [mu] m construction waste micro-powder with water, adding sodium citrate, and performing wet grinding to obtain superfine construction waste slurry; mixing the superfine construction waste slurry with boric acid and a polymer electrolyte water reducing agent, performing wet grinding, and introducing CO2 for carbonization activation; the carbonized and activated construction waste micro powder is used for preparing mortar, and the mechanical property and the durability are obviously improved. The utilization rate of the construction waste is increased, the carbonization degree is increased, the concrete performance is enhanced, and meanwhile large-scale emission reduction and resource utilization of CO2 are achieved.
本发明公开了一种建筑垃圾微粉碳化再激活方法，属于建筑材料技术领域。所述的建筑垃圾微粉碳化再激活方法包括如下步骤：将20‑25μm建筑垃圾微粉与水混合并加入柠檬酸钠后湿磨，得到超细建筑垃圾浆料；将超细建筑垃圾浆料与硼酸、聚合物电解质减水剂混合后湿磨并通入CO2进行碳化激活。将碳化激活后的建筑垃圾微粉用于制备砂浆，力学性能和耐久性能均得到明显提高。本发明提高了建筑垃圾的利用率，并在提高碳化程度和增强混凝土性能的同时实现了CO2的大规模减排及资源化利用。
