Abstract

The invention discloses a high-iron sulphoaluminate cement gelled material for a 3D printed house. The gelled material is mainly prepared from the following raw materials: high-iron sulphoaluminate cement, inorganic powder, glass fiber, anhydrite, mine tailing sand, water glass, calcium carbonate, a water reducer, a coagulation accelerator, a retarder, metakaolin, mirabilite and a modifier. The high-iron sulphoaluminate cement gelled material for the 3D printed house is reasonable in formula, convenient in material taking, good in cohesiveness and strong in stability, and has good out-of-pump shape keeping ability and bond properties, and a printed building has excellent properties including early strength, high strength, fire resistance, flame retardance, sound absorption and insulation, thermal insulation, good volume stability, super-strong weather resistance and the like, and requirements of construction continuity and construction strength of 3D printed buildings can be met, so as to ensure that building construction has good overall stability and use safety. Moreover, the preparation method is simple and is convenient to implement.

Description

Technical field [0001] The invention relates to the field of building materials, in particular to a high-iron sulfoaluminate cement cementitious material for 3D printing houses. Background technique [0002] 3D printing (3D printing) is a kind of rapid prototyping technology. It is a technology that uses powdered metal or plastic and other bondable materials to construct objects based on digital model files by printing layer by layer. 3D printing is usually achieved using digital technology material printers. It is often used to make models in mold manufacturing, industrial design and other fields, and then gradually used in the direct manufacturing of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, guns, and other fields....
