Coastal special-shaped structure 3D printing concrete, and processing technology and application thereof
The invention particularly relates to coastal special-shaped structure 3D printing concrete, and a processing technology and application thereof. Existing coastal special-shaped structure 3D printingconcrete also has the following defects that a coastal special-shaped structure applied to 3D printing by a conventional marine anticorrosion technology is not ideal in anticorrosion effect, and in addition, interlayer interface bonding and thixotropy of a conventional 3D printing material also have defects. The invention provides the coastal special-shaped structure 3D printing concrete. The coastal special-shaped structure 3D printing concrete comprises the raw materials: compound cement, reclaimed sand, fly ash, polyvinyl alcohol, graphene oxide, steel fibers, organic fibers, a water reducing agent, a thickening time control agent, a mineral admixture and water. The 3D printing concrete has good cohesive water retention and adjacent thin layer interface cohesiveness, a micro capacitor is formed by combining GO and PVA electrolyte, formation of a corrosion battery in a concrete thin layer is avoided, and the 3D printing concrete has good ocean durability and has good application prospects when applied to coastal special-shaped structure engineering.
本发明具体涉及一种滨海异型结构3D打印混凝土、加工工艺及应用。现有滨海异型结构3D打印混凝土还具有以下缺陷：常规海洋防腐技术应用于3D打印的滨海异型结构防腐效果不理想，另外，常规3D打印材料层间界面粘结与触变性还存在不足。本发明提供了一种滨海异型结构3D打印混凝土，其原料为复配水泥、再生砂、粉煤灰、聚乙烯醇、氧化石墨烯、钢纤维、有机纤维、减水剂、调凝剂、矿物掺合料和水。该3D打印混凝土拥有良好的粘聚保水性与相邻薄层界面粘结性，通过GO与PVA电解液结合形成微电容器避免混凝土薄层中腐蚀电池的形成，具有良好的海洋耐久性，应用于滨海异型结构工程具有良好的应用前景。
