RAW MATERIAL MIXTURE FOR ADDITIVE CONSTRUCTION PRODUCTION BY MATERIAL EXTRUSION Russian patent published in 2022 - IPC C04B28/04 C04B111/20 B33Y70/00 

Abstract RU 2781163 C1

FIELD: construction materials.

SUBSTANCE: invention relates to the field of construction materials industry and can be used for the manufacture of building products and structures in additive manufacturing technology by layer-by-layer extrusion (3D printing) of a raw mixture. The raw material mixture for additive construction production by the method for material extrusion includes, wt. %: Portland cement containing, wt. %: tricalcium silicate 68.1, tricalcium aluminate 7.2, 21.0-23.0, quartz sand with a size modulus of 2.2-2.4 and a humidity of 1-2% 59.14-62.22, MasterGlenium 430 superplasticizer based on polycarboxylate esters 0.21-0.23, methylsilantriol potassium salt “GKZH-11K” 0.011-0.012, binary mixture of finely ground pozzolan component diatomite with a hydraulic activity of at least 1500 mg/g, a grinding degree of at least 1400 m2/kg 2.1-2.3 and a finely ground component kaolin with a hydraulic activity of 627.3 mg/g, a grinding degree of at least 1800 m2/kg 2.1-2.3, water 12,359-13,018.

EFFECT: reduction in the consumption of Portland cement and superplasticizer in the raw material mixture, an increase in shape stability and ensuring the absence of defects in the form of ruptures of printed layers from the raw material mixture with the possibility of its extrusion on construction 3D printers implementing the method for layer–by-layer extrusion, a reduction in shrinkage deformations, water absorption and an increase in the bending strength of hardened composites printed on a 3D printer.
