Method for preparing high-strength fabricated artificial stone from construction waste
The invention discloses a method for preparing high-strength fabricated artificial stone from construction waste, which comprises the following steps: reselecting and separating brick concrete construction waste, and grinding concrete in a hot air autogenous mill to obtain recycled aggregate and micro powder; adding a calcareous material into the micro powder, grinding by using steam kinetic energy, and then carrying out rapid thermal activation in a countercurrent heater to obtain active micro powder; and adding an excitant, a reinforcing agent, a surfactant, a water repellent and water intothe active micro powder, uniformly stirring, molding and curing to obtain the high-strength fabricated artificial stone. The method is low in production cost and high in efficiency, and high-quality cyclic utilization of resources is achieved.
本专利公开了一种建筑垃圾制备高强装配式人造石的方法，将砖砼建筑垃圾通过重选分离，将砼在热风自磨机中研磨得到再生骨料和微粉；在微粉中加入钙质料后、用蒸汽动能粉磨、接着在逆流加热器中快速热活化，得到活性微粉；在活性微粉中加入激发剂、增强剂、表面活性剂、憎水剂、水，搅拌均匀、成型、养护后得到高强装配式人造石。本方法生产成本低，效率高，实现资源高质循环利用。
