Carbon dioxide cured ardealite-based cementing material and preparation method thereof
The invention discloses a carbon dioxide cured ardealite-based cementing material and a preparation method thereof, the preparation method comprises the following steps: S1, obtaining an ardealite-based cementing material, and pretreating the ardealite-based cementing material to obtain recycled aggregate particles; s2, obtaining an expired dairy product, and heating the expired dairy product at 60-80 DEG C for 1-2 hours; s3, adding the recycled aggregate particles into the expired dairy product, and mixing and stirring for 20-40 minutes under the condition of 100-140 DEG C to obtain a mixture; and S4, cooling the mixture to room temperature, adding yeast, carrying out dripping spraying under negative pressure and ultrasonic conditions, and maintaining for 2 hours under the negative pressure and ultrasonic conditions to obtain the carbon dioxide-maintained phosphogypsum-based cementing material. According to the method, the solid waste cementing material can be efficiently cured in an energy-saving mode, the obtained cured cementing material has good mechanical performance, and technical support can be provided for recycling and reusing of the solid waste material.
本发明公开了一种二氧化碳养护磷石膏基胶凝材料及其制备方法，所述制备方法包括以下步骤：S1：获取磷石膏基胶凝材料，并对所述磷石膏基胶凝材料进行预处理，获得再生骨料颗粒；S2：获取过期奶制品，并对所述过期奶制品在60‑80℃条件下加热处理1‑2h；S3：向所述过期奶制品中加入所述再生骨料颗粒，并在100‑140℃条件下混合搅拌20‑40min，获得混合物；S4：将所述混合物冷却至室温，加入酵母，并在负压和超声条件下进行滴淋，然后保持负压和超声条件养护2h，获得所述二氧化碳养护磷石膏基胶凝材料。本发明能够高效节能地对固废胶凝材料进行养护，且获得的养护胶凝材料具有较好的力学性能，能够为固废材料的回收再利用提供技术支持。
