Self-thermal-insulation building material based on cement-fly ash waste and preparation method of self-thermal-insulation building material
The invention provides a cement-fly ash waste-based self-insulation building material, which is prepared from the following ingredients in parts by weight: 60 to 80 parts of fly ash, 20 to 30 parts of cement, 10 to 20 parts of slag powder, 1 to 8 parts of silica fume, 3 to 10 parts of ardealite and 10 to 15 parts of expanded perlite. The foaming agent, the accelerator, the polycarboxylic acid water reducing agent and the straw particles are sequentially arranged from top to bottom, and the water-cement ratio is 0.45-0.55. The foaming agent, the accelerator, the polycarboxylic acid water reducing agent and the straw particles are sequentially arranged from top to bottom. According to the invention, the expanded perlite is modified, and the composite foaming agent is adopted, so that the green self-insulation building material with good performance is prepared. According to the self-insulation building material disclosed by the invention, the fly ash and the slag are used as main cementing materials, so that the reutilization of solid wastes such as the fly ash and the like is realized, the environmental pollution is reduced, the production cost of the building material is reduced, and the strength of the material can be enhanced while the heat conductivity coefficient and the quality of the material are reduced; the wall insulation requirement is met, and the energy-saving and environment-friendly effects are achieved.
本发明提供了一种基于水泥‑粉煤灰废弃物的自保温建筑材料，所述自保温建筑材料，包括按重量份数计的以下组分：粉煤灰60‑80份、水泥20‑30份、矿渣粉10‑20份、硅灰1‑8份、磷石膏3‑10份、膨胀珍珠岩10‑15份，发泡剂0.5‑2份、速凝剂0.5‑2份、聚羧酸减水剂0.5‑1.5份、秸秆颗粒3‑5份，水灰比0.45‑0.55。本发明通过对膨胀珍珠岩进行改性处理，以及采用复合发泡剂，制备得到具有良好性能的绿色自保温建筑材料。本发明的自保温建筑材料以粉煤灰和矿渣为主要胶凝材料，不仅实现了粉煤灰等固体废弃物的再利用，减轻了环境污染，降低了建筑材料的生产成本降低生成本，而且在降低材料导热系数和质量的同时还能够增强材料的强度，满足墙体保温要求，实现节能环保的效果。
