Composite geopolymer accropode and 3D printing method
The invention discloses a 3D printing method for a composite geopolymer accropode. The 3D printing method comprises the steps that S100, kaolin is subjected to high-temperature calcination, and metakaolin micro powder is obtained; s200, grinding the blast furnace slag to obtain blast furnace slag micro powder; s300, mixing the high-modulus water glass solution with a sodium hydroxide solution to obtain a low-modulus water glass solution serving as an alkaline activator; s400, mixing the metakaolin micro powder, the blast furnace slag micro powder and the alkaline activator, and uniformly stirring at a high speed to generate N-A-S-H gel with a three-dimensional network structure; s500, adding the mixed fiber, the water reducing agent, the bacteriostatic agent and the waterproof agent, and uniformly stirring at a low speed to obtain a flowable paste mixture; and S600, a 3D printing spray head is driven to move in the X direction, the Y direction and the Z direction along the accropode, meanwhile, a conveying pump drives the paste mixture to be quantitatively sprayed out of the 3D printing spray head, and the accropode is printed. According to the accropode printed through the method, the geopolymer is used for replacing a concrete material, environmental protection and energy saving are achieved, and the durability and the seawater erosion resistance are both enhanced.
本发明公开了一种复合型地聚物扭王字块3D打印方法，步骤包括：S100.高岭土经过高温煅烧得到偏高领土微粉；S200.高炉矿渣经过磨粉得到高炉矿渣微粉；S300.高模数水玻璃溶液和氢氧化钠溶液混合得到低模数水玻璃溶液作为碱性激发剂；S400.将偏高岭土微粉、高炉矿渣微粉及碱性激发剂混合并高速搅拌均匀，以产生三维网状结构的N‑A‑S‑H凝胶；S500.加入混合纤维、减水剂、抑菌剂和防水剂，低速搅拌均匀，得到流动性膏状混合物；S600.驱动3D打印喷头沿着扭王字块作X、Y、Z三向运动，同时输送泵驱动所述膏状混合物从3D打印喷头定量喷吐，打印扭王字块。通过这种方法3D打印的扭王字块，以地聚物为替代混凝土材料，环保节能，耐久性、抵抗海水侵蚀能力均得到增强。
