Unreinforced self-reinforced cement-based printing concrete and preparation method thereof
The invention discloses an unreinforced self-reinforced cement-based printing concrete and a preparation method thereof, and belongs to the technical field of 3D printing concrete. The unreinforced self-reinforced cement-based printing concrete comprises the following components in parts by weight: 100 parts of a cementing mixed material, 0.3 to 2.0 parts of a chemical modifying material, which comprises clay powder, an efficient strong plasticizer and a mineral additive; 147 to 175 parts of aggregate; and 33 to 49 parts of water; wherein the doping amount of fibers is 1.5-2.3 kg/m<3>. Material configuration parameters, printing process parameters and structural performance parameters are taken as design objectives, and the requirements of working performance, extrusion performance, self-supporting performance, construction performance, working time and mechanical performance under an unreinforced condition are met. The prepared unreinforced self-reinforced cement-based printing concrete can meet the requirement of large-scale building construction of 3D printing concrete under an unreinforced condition.
本发明公开了一种无筋自强水泥基打印混凝土及配制方法，属于3D打印混凝土技术领域。无筋自强水泥基打印混凝土包括如下单位体积质量的组分：胶结混合材料：100份，化学改性材料0.3‑2.0份，包括黏土粉、高效大幅塑化剂、矿物外加剂；集料：147‑175份；水：33‑49份；纤维掺入量为1.5‑2.3kg/m。本发明以材料配置参数、打印工艺参数和结构性能参数为设计目标，满足无筋条件下工作性能、挤出性能、自支撑性能、建造性能、工作时间和力学性能要求。所配置的无筋自强水泥基打印混凝土可满足无筋条件下3D打印混凝土的规模化建造施工。
