3D printing low-carbon concrete mortar, preparation method and application
The invention discloses 3D (three-dimensional) printing low-carbon environment-friendly concrete mortar, a preparation method and application, and the 3D printing low-carbon environment-friendly concrete mortar is prepared from the following raw materials in parts by weight: 40 to 80 parts of Portland cement, 40 to 80 parts of aluminate cement, 100 to 200 parts of solid waste cementing material, 140 to 300 parts of fine aggregate and 0.1 to 0.5 part of water-retaining agent, the high-performance concrete is prepared from the following components in parts by weight: 0.1-0.4 part of an interface activator, 0.4-0.8 part of a complexing agent, 10-15 parts of alumina powder, 0.5-1.0 part of a high-efficiency water reducing agent, 0.2-3.0 parts of a surface film-forming agent, 0.7-6.0 parts of a functional composite penetrant and 200-880 parts of water. The problem of poor waterproof and thermal insulation performance caused by common interlayer structure strength performance of existing 3D printing mortar is solved.
本发明公开了一种3D打印低碳环保混凝土砂浆、制备方法及应用，各原料以重量份计包括：硅酸盐水泥40‑80份，铝酸盐水泥40‑80份、固废胶凝材料100‑200份、细骨料140‑300份、保水剂0.1‑0.5份，界面激发剂0.1‑0.4份、络合剂0.4‑0.8份、氧化铝粉10‑15份、高效减水剂0.5‑1.0、表面成膜剂0.2‑3.0份、功能性复合渗透剂0.7‑6.0份，水200份‑880份。解决现有3D打印砂浆的层间结构强度性能一般致使导致防水保温性能差的问题。
