Artificial fine stone aggregate as well as preparation method and application thereof
The invention provides artificial fine stone aggregate as well as a preparation method and application thereof, and relates to the technical field of building waste recovery. The artificial fine stone aggregate provided by the invention comprises a concrete residue inner core and an ultrahigh concrete skin material coated on the surface of the concrete residue inner core. The concrete residues are used as the main component of the artificial fine stone aggregate core, so that the concrete residues are reused, natural resources are saved, and environmental pollution is reduced. And meanwhile, the concrete residue inner core is packaged by the ultrahigh concrete skin material, so that the bearing capacity strength of the artificial fine stone aggregate meets engineering use. Furthermore, the concrete residues are activated by doping an exciting agent, so that the bearing capacity strength of the artificial fine stone aggregate is further improved. According to the result of the embodiment of the invention, the single-particle bearing capacity strength of the artificial fine stone aggregate is 2.50-2.70 MPa.
本发明提供了一种人造细石骨料及其制备方法和应用，涉及建筑废弃物回收技术领域。本发明提供的人造细石骨料，包括混凝土残渣内核和包覆在所述混凝土残渣内核表面的超高混凝土皮料。本发明采用混凝土残渣作为人造细石骨料内核的主要成分，实现混凝土残渣的再次利用，节约自然资源，减少了环境污染。同时超高混凝土皮料对混凝土残渣内核进行封装，使人造细石骨料的承载力强度满足工程使用。进一步地，本发明通过掺入激发剂对混凝土残渣进行活化处理，进一步提高人造细石骨料的承载力强度。由本发明实施例结果可知，所述人造细石骨料的单颗粒承载力强度为2.50～2.70MPa。
