Double-system composite high-strength unfired lightweight aggregate as well as preparation method and application thereof
The invention discloses a double-system composite high-strength unfired lightweight aggregate as well as a preparation method and application thereof. Thiourea slag, desulfurized gypsum and fly ash are taken as a mixture, the mixture and water are mixed and stirred evenly, an additive is added, stirring is conducted again, and a semi-slurry mixture is obtained; granulating the semi-slurry mixture to form an inner core blank; uniformly preparing a shell mixture layer on the surface of the inner core blank to obtain lightweight aggregate balls; and naturally curing the lightweight aggregate balls, pre-drying, and finally pressurizing, carbonizing and curing to obtain the dual-system composite high-strength unfired lightweight aggregate. The prepared lightweight aggregate has the advantages of high early strength, low bulk density, low water absorption and the like, can be widely applied to various ranges, and has the characteristics of high solid waste resource utilization degree, energy conservation, low consumption, low price and the like.
本发明公开了一种双体系复合型高强免烧轻骨料及其制备方法和应用。取硫脲渣、脱硫石膏、粉煤灰作为混料，混料和水混合并搅拌均匀，加入外加剂再次搅拌，得到半浆体混合料；将半浆体混合料造粒，形成内核坯料；在内核坯料的表面均匀制备外壳混合剂层，得到轻骨料圆球；将轻骨料圆球进行自然养护后预干燥，最后加压碳化养护，得到所述双体系复合型高强免烧轻骨料。本发明制备的轻骨料具有早期强度高、堆积密度低、吸水率小等优点，能广泛适用于多种范围，具有固废资源利用化程度高、节能低耗、价格低廉等特点。
