Anti-freezing concrete for 3D printing in low-temperature environment and construction method of anti-freezing concrete
The invention discloses anti-freezing concrete for 3D printing in a low-temperature environment. The anti-freezing concrete comprises, by weight part, 90 to 125 parts of a cementing material, 80-105 parts of sand, 5-15 parts of water-borne epoxy resin, 6-12 parts of shell powder, 4-9 parts of bentonite, 0.5-1 part of anti-dispersion fibers, 2-8 parts of a water reducing agent, 0.6-4 parts of an air entraining agent, 8-14 parts of an anti-freezing agent, 0.15-0.3 part of a retarder, 0.5-1.5 parts of a flocculating agent and 30-70 parts of water, wherein the cementing material comprises 55-85 parts of cement and 15-40 parts of ultrafine powder. The anti-freezing concrete provided by the invention has good anti-freezing performance and mechanical properties, is suitable for 3D printing in a low-temperature environment, and realizes unmanned construction and mold-free construction in a special climatic environment.
本发明公开了一种用于低温环境下3D打印的抗冻混凝土，以重量份数计，所述抗冻混凝土包括胶凝材料90‑125份、砂80‑105份、水性环氧树脂5‑15份、贝壳粉6‑12份、膨润土4‑9份、抗分散纤维0.5‑1份、减水剂2‑8份、引气剂0.6‑4份、抗冻剂8‑14份、缓凝剂0.15‑0.3份、絮凝剂0.5‑1.5份和水30‑70份；所述胶凝材料包括水泥55～85和超细粉15～40。本发明提供的抗冻混凝土具有良好抗冻性能和力学性能，适用于低温环境下3D打印，实现特殊气候环境下无人建造，免模施工。
