Fiber-reinforced cement-based composite material for 3D printing and preparation method thereof
The invention discloses a fiber-reinforced cement-based composite material for 3D printing. The composite material comprises the following raw materials in parts by weight: 1 part of cement, 0.2-0.8 part of mineral admixture, 0.3-1.0 part of fine aggregate, 0.4-0.7 part of water, 0.001-0.006 part of water reducing agent, 0.0004-0.002 part of accelerator, 0.0008-0.004 part of retarder, 0.001-0.004part of defoaming agent, 0.001-0.007 part of thickener, 0.01-0.07 parts of latex powder, and 0.01-0.06 parts of stainless steel fibers. The material provided by the invention not only has good fluidity, extrudability and modeling, but also has high mechanical properties and chlorine salt corrosion resistance, and is suitable for maritime work environment.
本发明公开了一种用于3D打印的纤维增强水泥基复合材料，所述复合材料的原料种类及各原料的重量份数为：水泥1份，矿物掺合料0.2～0.8份，细集料0.3～1.0份，水0.4～0.7份，减水剂0.001～0.006份，速凝剂0.0004～0.002份，缓凝剂0.0008～0.004份，消泡剂0.001～0.004份，增稠剂0.001～0.007份，乳胶粉0.01～0.07份，不锈钢纤维0.01～0.06份。本发明该材料不仅具有较好的流动性，可挤出性和建造型，同时具有较高的力学性能与抗氯盐侵蚀性能，适用于海工环境。
