3D printing straw concrete material and preparation method thereof
The invention discloses a 3D printing straw concrete material and a preparation method thereof, and the 3D printing straw concrete material comprises the following components in percentage by weight: 21.02% to 35.06% of cement, 2.56% to 10.21% of straw ash, 5.74% to 10.93% of stone powder, 0.14% to 0.56% of straw fiber, 38.16% to 53.64% of fine aggregate, 0.3% to 0.45% of a water reducing agent, 0.03% to 0.045% of a defoaming agent, 10.79% to 14.55% of water and 0.39% to 1.18% of drying oil. According to the prepared straw concrete material for 3D printing, by adding the straw ash, the delayed coagulation influence of a gelling component caused by the straw fibers is relieved, the material cost is low, the material taking range is wide, and the prepared straw concrete has the advantages of being high in strength, light, capable of preserving heat and insulating heat and the like and meets the development requirements of the environment-friendly type 3D printing technology.
本发明公开了一种3D打印秸秆混凝土材料及其制备方法，所述3D打印混凝土材料，按照重量百分数计，包括以下各组分：水泥21.02％～35.06％、秸秆灰2.56％～10.21％、石粉5.74％～10.93％、秸秆纤维0.14％～0.56％、细骨料38.16％～53.64％、减水剂0.3％～0.45％、消泡剂0.03％～0.045％、水10.79％～14.55％、干性油0.39％～1.18％。本发明制备的3D打印秸秆混凝土材料，通过加入秸秆灰缓解了秸秆纤维造成的胶凝组分缓凝影响，并且材料成本低、取材广，制得的秸秆混凝土具有较高强度和轻质、保温、隔热等优点，符合绿色环保型3D打印技术的发展要求。
