3D printing lightweight concrete prepared from modified rubber 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 rubber 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, modified rubber powder, honeycomb ceramic particles, fibers, a defoaming agent, an accelerator, a water reducing agent, a thickening agent, an air entraining agent and water, the modified rubber powder is prepared by adding a mixture M into an activating agent solution, performing heating treatment and performing drying treatment, and the mixture M is a mixture of rubber powder and a surface modifier solution. The waste rubber tires and the waste honeycomb ceramics are recycled and applied to the 3D printing lightweight concrete, so that the cost and resources are saved, the environment is protected, and meanwhile, 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橡胶粉制备的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、改性橡胶粉、蜂窝陶瓷颗粒、纤维、消泡剂、速凝剂、减水剂、增稠剂、引气剂以及水；所述改性橡胶粉是由混合物M加入活化剂溶液中加热处理、并烘干处理而制得，其中，所述混合物M为橡胶粉与表面改性剂溶液的混合物。本发明将废弃橡胶轮胎、废弃蜂窝陶瓷资源化应用于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。
