Fly ash solid waste fiber non-fired ceramsite and preparation method thereof

The invention discloses fly ash solid waste fiber unfired ceramsite and a preparation method thereof. The fly ash solid waste fiber unfired ceramsite is prepared from the following components in percentage by mass: 70%-75% of fly ash, 10%-15% of straws, 1.0%-5.0% of furnace ash, 5.0%-10% of superfine slag powder, 1.0%-2.0% of sodium silicate, 1.0%-2.0% of desulfurized gypsum, 1.0%-2.0% of cement and 1.0%-2.0% of an additive. The fly ash solid waste fiber non-fired ceramsite is prepared from solid wastes such as fly ash, straws, furnace ash and superfine slag powder, so that on one hand, the production cost of the non-fired ceramsite is reduced, and on the other hand, a large amount of solid waste is consumed, and the utilization way of solid waste materials is broadened. 本发明公开了一种粉煤灰固废纤维免烧陶粒及其制作方法，其中，一种粉煤灰固废纤维免烧陶粒，通过以下组分按照质量百分比配制而成：粉煤灰70％～75％、秸秆10％～15％、炉灰1.0％～5.0％、矿渣微粉5.0％～10％、硅酸钠1.0％～2.0％、脱硫石膏1.0％～2.0％、水泥1.0％～2.0％、外加剂1.0％～2.0％。本发明利用粉煤灰、秸秆、炉灰、矿渣微粉等固废制备粉煤灰固废纤维免烧陶粒，一方面降低了免烧陶粒的生产成本；另一方面消纳了大量的固废，拓宽了固废材料的利用途径。
