Steel fiber reinforced concrete for 3D printing and preparation method thereof
The invention discloses steel fiber reinforced concrete for 3D printing and a preparation method of the steel fiber reinforced concrete. The steel fiber reinforced concrete comprises the following components in parts by weight: 12 parts of ordinary Portland cement, 0.6 part of a thickening time control agent, 12 parts of sand, 0.024 to 0.048 part of a water reducing agent, 0.010 to 0.018 part of athickening agent, 0.012 part of a defoaming agent, 3.3 to 3.6 parts of water, and short and straight steel fibers, wherein the volume of the steel fibers accounts for 0.5%-5% of the total volume of the material, and the diameter of an adopted printer nozzle is 20-40 mm. According to the printable performance of a cement-based material and the diameter of the printer nozzle, the short and straightsteel fibers with a corresponding length-diameter ratio and corresponding volume content are doped, so the 3D printing concrete has good printable performance and mechanical property, and the actualengineering application of the 3D printing concrete is promoted.
本发明公开了一种用于3D打印的钢纤维混凝土及其制备方法，该材料按重量份数计，其含量和组成分别为：普通硅酸盐水泥12份；调凝剂0.6份；砂12份；减水剂0.024～0.048份；增稠剂0.010～0.018份；消泡剂0.012份；水3.3～3.6份；短直钢纤维；其中，所述钢纤维的体积占所述材料总体积的0.5％～5％，所采用的打印机喷嘴为20‑40mm。本发明根据水泥基材料的可打印性能及打印喷嘴直径，掺入相应长径比和体积含量的短直钢纤维，使3D打印混凝土具有良好的可打印性能、力学性能，有利于推动3D打印混凝土的实际工程应用。
