3D printing geopolymer and 3D building printing method
The invention discloses a 3D printing geopolymer and a 3D building printing method. The 3D printing geopolymer is prepared from the following components in parts by weight: 100-1000 parts of silicon-aluminum oxide, 50-500 parts of hydroxide, 50-500 parts of carbonate, 50-500 parts of silicate, 1-10 parts of fluoride, 10-200 parts of filler and 50-1000 parts of water. The 3D building printing method comprises the steps of uniformly mixing silicon-aluminum oxide, hydroxide, carbonate, silicate and filler through a high-speed mixer, and then adding the mixture into a concrete mixer to be mixed and stirred with water to obtain a pasty geological mixture with fluidity; and printing the pasty mixture through a 3D printer to form a building with reserved reinforcing steel bar reinforcing holes, coating the surfaces of reinforcing steel bars with the pasty geological mixture after printing is completed, inserting the reinforcing steel bars into the reinforcing steel bar reinforcing holes, andobtaining the printed building. The material has the characteristics of good fluidity, good printing performance, high strength, rapid hardening, acid and alkali corrosion resistance, environmental protection, low energy consumption, low price and same properties as natural rocks, and is very suitable for 3D printing of high-strength buildings in combination with the printing method.
本发明公开了一种3D打印地质聚合物及其3D打印建筑的方法，3D打印地质聚合物包括以下组分：硅铝氧化物100‑1000重量份，氢氧化物50‑500重量份，碳酸盐50‑500重量份，硅酸盐50‑500重量份，氟化物1‑10重量份，填料10‑200重量份，水50‑1000重量份。本发明3D打印建筑的方法为：将硅铝氧化物、氢氧化物、碳酸盐、硅酸盐和填料用高速混合机混合均匀，再加入到混泥土搅拌机中用水进行混合搅拌，得到具有流动性的膏状地质混合物；将膏状混合物通过3D打印机打印出具有预留钢筋加强孔的建筑物，打印完成后，将钢筋表面涂覆表面涂覆膏状地质混合物，并插入钢筋加强孔中，得到打印建筑。该材料具有流动性好、打印性能好、强度高、硬化快、耐酸碱腐蚀、绿色环保、能耗低、价格低廉、性质与天然岩石相同的特点，结合打印方法非常适用于3D打印高强度建筑。
