Abstract

The invention relates to the field of 3D printing building materials, in particular to a 3D printing alkali-activated geopolymer composite material doped with hibiscus cannabinus bast fiber crop straw, and a preparation method thereof. The composite material comprises hibiscus cannabinus bast fiber crop straw, slag, fly ash, water glass, sodium hydroxide, lignin and water. The kenaf bast fiber, the kenaf straw core and the slag are doped into the alkali-activated fly ash-based geopolymer composite material for 3D printing, so that the stacking performance can be improved, the problems that a common 3D printing material is low in early strength, poor in shape retention, easy to crack, poor in extrusion fluidity and the like are solved, industrial and agricultural solid waste recycling is achieved, application in the intelligent construction field such as additive manufacturing is achieved, and good environmental benefits, economic benefits and social benefits are achieved.

Description

technical field

[0001] The invention relates to the field of 3D printing building materials, in particular to a 3D printing alkali-activated geopolymer composite material mixed with kenaf bast fiber crop straw and a preparation method thereof. Background technique

[0002] In the field of construction, 3D printing technology has the advantages of high efficiency, low cost, less pollution, and intelligence compared with traditional construction technology, especially in the intelligent construction of special-shaped buildings and component parts. Materials limit the application and development of 3D printing technology in the construction industry. For 3D printing building materials, low cost, environmental protection and waste, low carbon and printability are the key points for its future development.

[0003] At present, cement-based materials and geopolymer materials are widely used in the field of architectural 3D printing materials. However, there is a problem of high ...
