一种利用再生混凝土细粉制备高活性辅助性胶凝材料的方法

By using wind-driven suspension carbonation to process recycled concrete fine powder, spheroidal calcium carbonate "capsules" are formed, which solves the problems of low reactivity and high water absorption of RCF in cement-based composite materials, and improves the performance and application efficiency of the materials.

Abstract

本发明属于辅助性胶凝材料制备技术领域,更具体的说是涉及一种利用再生混凝土细粉制备高活性辅助性胶凝材料的方法。本发明使用氨水将RCF浸润,随后经风力悬浮碳酸化处理得到高活性辅助性胶凝材料,风力悬浮碳酸化(WSC)处理,重新组装了RCF的颗粒结构,形成由碳酸钙“胶囊”包裹的RCF,通过NH3·H2O溶液作为晶型控制剂,能诱导在RCF表面形成球霰石型碳酸钙,这种方法形成的球霰石“胶囊”不仅仅降低了RCF的吸水性,还提升了反应活性。
