Solid-phase-foamed fly ash-silicon calcium slag unfired ceramsite and preparation method thereof
The invention belongs to the technical field of horticultural materials, and particularly relates to solid-phase-foamed fly ash-silicon calcium slag unfired ceramsite and a preparation method thereof. The olid-phase-foamed fly ash-silicon calcium slag unfired ceramsite is prepared from the following raw materials in parts by weight: 30-75 parts of fly ash, 15-50 parts of silicon-calcium slag, 5-15 parts of carbide slag, 1-2 parts of desulfurized gypsum, 1-5 parts of ammonium sulfate and 30-50 parts of water. According to the invention, ammonium sulfate is creatively adopted as a pore-forming agent, and pores are formed in the surface and the interior of the ceramsite through solid-phase foaming, so the solid-phase-foamed fly ash unfired ceramsite is obtained. Ammonium sulfate particles generate ammonia in an alkaline environment, ammonia gas is released under an oxygen steaming condition, bubbles are formed in the ceramsite, and therefore, pore forming is achieved. The residual foaming agent, namely ammonium sulfate can provide a nitrogen fertilizer for plants; and the used silicon-calcium slag not only can realize waste utilization, but also can improve the later strength of the product.
本发明属于园艺材料技术领域，具体涉及一种固相发泡粉煤灰硅钙渣免烧陶粒及其制备方法，由以下重量份的原料组成：粉煤灰30‑75份、硅钙渣15‑50份、电石渣5‑15份、脱硫石膏1‑2份、硫酸铵1‑5份和水30‑50份。本发明创造性地采用硫酸铵作为造孔剂，通过固相发泡，在陶粒表面及内部造孔，得到固相发泡粉煤灰免烧陶粒。硫酸铵颗粒在碱性环境中产生氨，在蒸氧下氨气释放，在陶粒中形成气泡，从而实现造孔。残留的发泡剂硫酸铵可为植物提供氮肥；使用的硅钙渣既可以实现废物利用，又可以提高产品后期的强度。
