Abstract

The invention discloses a low-alkalinity sulphoaluminate cement gel material for house 3D printing. The low-alkalinity sulphoaluminate cement gel material is prepared from low-alkalinity sulphoaluminate cement, inorganic powder, alkali resistant glass fibers, calcium carbonate, a water reducer, a coagulation accelerator, a delayed coagulant, metakaolin, saltcake and a modifier. The low-alkalinity sulphoaluminate cement gel material has a reasonable formula, is prepared from easily available materials, has good material caking properties and good stability and has a good pump-out form keeping capability and bonding properties. A build prepared from the low-alkalinity sulphoaluminate cement gel material has low alkalinity, high early strength, fire prevention, flame retardation, water prevention, immersion resistance, sound absorption, sound insulation, thermal insulation, thermal insulation, good volume stability and super strong weatherability, and satisfies building 3D printing construction continuity and building strength requirements so that the building has good integral stability and use safety.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a low-alkalinity sulfoaluminate cement gelling material for 3D printing houses. Background technique [0002] 3D printing (3D printing) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture 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, firearms, and others. ...
