Powder solid waste-based unfired foamed ceramsite and preparation method thereof
The invention discloses powder solid waste-based unfired foamed ceramsite and a preparation method thereof, and belongs to the technical field of ceramsite production. The foamed ceramsite is prepared from the following materials in parts by mass: 70-90 parts of powder solid waste, 10-30 parts of a hydraulic cementing material, 0.5-1 part of a water reducing agent, 0.2-1 part of a foaming agent and the balance of water, and the water-cement ratio is 0.3-0.4. Foaming slurry prepared at normal temperature is extruded in an extrusion mode, then the extruded foaming slurry is cut by a high-frequency steel wire to form a ball blank, and finally the ball blank is put into a ball forming disc to prepare the ball. The problems of low porosity, high density, low strength and the like of the existing unfired ceramsite are fundamentally solved, the resource utilization of solid wastes is realized, and the method has the characteristics of simple process, low cost, energy conservation, low carbon, environmental protection and the like.
本申请公开了一种粉体固废基免烧发泡陶粒及其制备方法，属于陶粒生产技术领域。本申请发泡陶粒的材料组成按质量份数配比计为：粉体固废70～90份，水硬性胶凝材料10～30份，减水剂0.5～1份，发泡剂0.2～1份，其余为水，水灰比0.3‑0.4。本申请通过挤压的方式将常温下制备的发泡浆体挤出，然后将挤出的发泡浆体利用高频钢丝切割形成球胚，最后将球胚放入成球盘中制得。本申请不仅从根本上克服了现有免烧陶粒低孔隙率、高密度和低强度等问题，而且实现了固体废弃物的资源化利用，具有工艺简单、成本低、节能、低碳环保等特点。
