3D printing concrete capable of absorbing waste glass powder and preparation method thereof

The invention discloses 3D printing concrete capable of absorbing waste glass powder and a preparation method thereof, and belongs to the technical field of concrete materials and preparation thereof. The 3D printing concrete capable of consuming the waste glass powder, provided by the invention, is prepared from the following raw materials in parts by weight: 796.45 to 937 parts of ordinary Portland cement, 33.9 to 140.55 parts of the waste glass powder, 80 parts of sulphoaluminate cement, 79.1 to 113 parts of silica fume, 395.5 parts of water, 1000 parts of river sand, 0.45 part of cellulose ether, 2.26 parts of a water reducing agent, 2.37 parts of a de-foaming agent and 2.7 parts of rubber powder. By reasonably using the waste glass powder, the environment-friendly 3D printing concrete material which is suitable for an extrusion type 3D printing concrete technology and has good printability is prepared, meanwhile, the concrete strength is improved, the pore structure is refined, the carbon emission is red
