3D printing building ink formula based on red mud solid waste recycling
The invention discloses a 3D printing building ink formula based on red mud solid waste recycling. The ink formula comprises a gel material, a solid waste material, an active material, aggregate, a stabilizer, a polycarboxylate superplasticizer and water. According to the formula of the ink, dry powder materials are mixed and stirred at the stirring speed of 30-40 r/min and the stirring temperature of 10-28 DEG C, the dry powder materials are stirred for 2-3 minutes firstly, water is continuously added for stirring, and the stirring time is 180-300 s. The red mud is used for replacing cement and other cementing materials, the red mud can be used as a raw material for 3D building printing, the utilization rate of the red mud can be increased to 28% under the condition that different strength requirements are met, waste is turned into wealth, the red mud can be subjected to resource utilization, the utilization rate of preparing cement from clay is greatly reduced, and the cost is reduced. The energy utilization can be reduced, the carbon emission can be reduced, the material can be repeatedly utilized to become a raw material for buildings, and economic and social benefits are created.
本发明公开了一种基于赤泥固废回收利用的3D打印建筑油墨配方，该油墨配方包括凝胶材料、固废材料、活性材料、骨料、稳定剂、聚羧酸高效减水剂和水；本油墨配方由干粉料混合进行搅拌，搅拌速率为30～40r/min，搅拌温度为10～28℃，先干粉搅拌2‑3分钟，继续加水进行搅拌，搅拌时间为180～300s。本发明以赤泥替代水泥等胶凝材料，可以将它作为3D打印建筑打印的原材料进行使用，在满足不同强度需求的情况下，并且可以将赤泥利用率提高到28％，变废为宝，不但可以将赤泥进行资源化利用，大大减少了粘土制作水泥的利用，又能减少能源的利用，减少碳的排放，又能重复利用变成建筑的原材料，创造经济和社会效益。
