Multi-solid-waste non-sintered ceramsite based on phosphogypsum and preparation method of multi-solid-waste non-sintered ceramsite
The invention belongs to the field of building materials, and discloses multiple solid waste non-sintered ceramsite based on phosphogypsum and a preparation method thereof.The non-sintered ceramsite is prepared from, by mass, 35%-70% of phosphogypsum, 10%-30% of fly ash, 5%-20% of phosphate tailings and 5%-15% of cement. The water and the additive respectively account for 25%-33% and 0%-3% of the total amount of the phosphogypsum, the fly ash, the phosphate tailings and the cement mixture; the preparation method comprises the following steps: uniformly stirring ardealite, fly ash, phosphate tailings, cement and an additive aqueous solution to form a mixture, granulating with water, and finally aging and curing to obtain the unfired ceramsite. The process method disclosed by the invention is relatively simple and low in cost, a large number of solid waste materials are utilized, and the prepared ceramsite can be widely applied to industries such as ceramsite concrete, cement concrete blocks, sound insulation walls, highway subgrade materials and the like.
本发明属于建筑材料领域，公开了一种基于磷石膏的多种固废免烧陶粒及其制备方法，本发明免烧陶粒包括以下质量百分比：磷石膏35‑70％、粉煤灰10‑30％、磷尾矿5‑20％、水泥5‑15％,水和外加剂分别占磷石膏、粉煤灰、磷尾矿、水泥混合物总量的25％‑33％、0％‑3％；先将磷石膏、粉煤灰、磷尾矿、水泥、外加剂水溶液搅拌均匀形成混合料，然后水进行造粒，最后进行陈化、养护即得免烧陶粒。本发明工艺方法较为简单、成本低，大量利用多种固废材料，制成的陶粒可广泛应用于陶粒混凝土、水泥混凝土砌块、隔音墙、公路路基材料等行业。
