3D printing lightweight concrete prepared from modified waste ceramic powder and preparation method thereof
The invention relates to the technical field of building materials, in particular to 3D printing lightweight concrete prepared from modified waste ceramic powder and a preparation method of the 3D printing lightweight concrete. The 3D printing lightweight concrete is prepared from the following components: cement, a mineral admixture, ceramic powder, machine-made sand, fibers, other auxiliaries and water, the ceramic powder is modified waste ceramic powder; or the ceramic powder is a mixture of modified waste ceramic powder and unmodified ceramic powder; the unmodified ceramic powder is first ceramic powder with the specific surface area of 230-450m < 2 >/kg; the modified waste ceramic powder is prepared by adding an active agent into the mixture M and carrying out ball milling treatment; wherein the mixture M is a mixture prepared by heating, stirring and drying second ceramic powder and a modifier solution. The waste ceramic is recycled and applied to the 3D printing lightweight concrete, so that the cost and resources are saved, the environment is protected, and the provided 3D printing lightweight concrete has good fluidity, extrudability, constructability and durability.
本发明涉及建筑材料技术领域，特别涉及一种用改性废弃陶瓷粉制备的3D打印轻质混凝土及其制备方法。该3D打印轻质混凝土包括以下组分：水泥、矿物掺合料、陶瓷粉料、机制砂、纤维、其他助剂以及水；陶瓷粉料为改性废弃陶瓷粉；或，陶瓷粉料为改性废弃陶瓷粉和未改性陶瓷粉的混合物；未改性陶瓷粉为比表面积为230～450m2/kg的第一陶瓷粉；改性废弃陶瓷粉是由混合物M加入活性剂球磨处理制得；其中，混合物M是由第二陶瓷粉与改性剂溶液经加热搅拌、烘干后制得的混合物。本发明将废弃陶瓷资源化应用于3D打印轻质混凝土中，在节约成本和资源、保护环境的同时，保障所提供的3D打印轻质混凝土具有良好的流动性、可挤出性、建造性以及耐久性。
