Solid-waste-based lightweight roof prefabricated material and preparation method thereof
The invention discloses a solid waste based lightweight roof prefabricated material and a preparation method thereof, the solid waste based lightweight roof prefabricated material is composed of the following components in parts by mass: 30-60 parts of solid waste based sulphoaluminate cement, 40-70 parts of semi-hydrated desulfurized gypsum, 0.2-0.4 part of a retarder, 0.02-0.2 part of a water reducer, 0-0.2 part of a gypsum retarder, and 5-15 parts of prefabricated foam; the water cement ratio is 0.2-0.4. Through the synergistic effect of the solid-waste-based sulphoaluminate cement and the semi-hydrated gypsum, the mechanical property is greatly improved in a short time, the requirement for light weight is met, and meanwhile rapid forming and demolding can be achieved through the early-strength and rapid-hardening characteristics.
本发明公开了一种固废基轻质屋面预制材料及其制备方法，固废基轻质屋面预制材料，按质量份计，由以下组分组成：固废基硫铝酸盐水泥30‑60份，半水脱硫石膏40‑70份，缓凝剂0.2‑0.4份，减水剂0.02‑0.2份，石膏缓凝剂0‑0.2份，预制泡沫5‑15份；水灰比为0.2‑0.4。固废基硫铝酸盐水泥与半水石膏的协同效应，短期大幅提升力学性能、满足轻质化需求，同时早强快硬特性可以实现快速成型脱模。
