Formula of 3D printing building material composed of solid waste
The invention discloses a formula of a 3D printing building material composed of solid waste. The formula specifically comprises cement, red mud, ash, ash slag, a water reducing agent, fiber, an inorganic additive and water, the solid waste red mud, ash and ash slag are used as main raw materials of the 3D printing building material formula, so that the use amount of cement in the building material is small. most of the materials are solid wastes, a 3D printing material formula capable of utilizing the solid wastes as the raw materials in a large scale by only needing a small amount of cement is realized, and the initial setting time of the material can be greatly shortened by using a very small amount of inorganic additives in the 3D printing material formula, so that the performance requirements of the 3D printing material are met. Meanwhile, the cost is reduced. The building material prepared according to the formula is good in early-stage fluidity, strong in shaping performance and short in initial setting time, and the final strength and the anti-pressure ability of the material formed in the later stage are high, so that the building material prepared according to the formula can better meet the characteristic requirements of a 3D printing material.
本发明公开了一种由固体废料组成的3D打印建筑材料的配方，该配方具体包括：水泥、赤泥、灰、灰渣、减水剂、纤维、无机添加剂和水，本发明利用固体废料赤泥、灰和灰渣来作为3D打印建筑材料配方的主要原材料，使得建筑材料中水泥用量少，大部分材料为固体废料，实现了一个只需少量水泥，便可规模化利用固体废料作为原材料的3D打印材料配方，且在该3D打印材料配方中使用极少量无机添加剂，可极大缩短材料的初凝时间，从而符合3D打印材料的性能要求，同时，按照该配方所制成的建筑材料前期流动性好，塑形性能强，初凝时间短，后期成型后材料的最终强度高，抗压能力强，使得该配方制得的建筑材料能够更加符合3D打印材料的特点要求。
