Abstract
The present disclosure provides a recycled powder concrete material for 3D printing construction and a preparation method therefor. The concrete material includes the following components by weight parts: cement: 1.0 part; recycled powder: 0.1-2.0 parts; recycled fine aggregate: 1.0-12.0 parts; nano titanium dioxide: 0.001-0.18 parts; high elastic modulus polyethylene fiber: 0.005-0.15 parts; redispersible latex powder: 0.002-0.1 parts; cellulose: 0.001-0.045 parts; activator: 0.01-0.30 parts; polycarboxylic acid water reducing agent: 0.005-0.2 parts; and water: 0.2-2.0 parts. According to the recycled powder concrete material for 3D printing construction, construction waste recycling powder technology is combined with 3D printing construction technology. The safety, applicability and durability of 3D printing recycled powder concrete material are further improved through the optimization of the recycled powder concrete formula. At the same time, the 3D printing recycled powder concrete material has self-cleaning functionality.
