Cold-consolidated artificial aggregate based on multi-source industrial waste and preparation method of cold-consolidated artificial aggregate
The invention discloses cold-consolidated artificial aggregate based on multi-source industrial waste and a preparation method thereof.The cold-consolidated artificial aggregate is prepared from, by mass, 100-200 parts of blast furnace slag, 300-400 parts of fly ash, 50-450 parts of carbide slag, 4-60 parts of alkali activator, 25-75 parts of coal gangue and 100 parts of water, the alkali activator comprises sodium silicate and NaOH, and the alkali activator comprises sodium silicate and sodium hydroxide; and the components respectively account for 2-30 parts and 2-30 parts of the total mass part. The integrity of the core-shell structure of the aggregate is improved through a disc balling process, the adhesive force is enhanced through surface pretreatment, the overall strength of the aggregate is improved, and the water absorption rate is reduced; the industrial waste is subjected to physical-chemical-internal three-stage combined activation treatment, so that the activity and durability are improved; the hydration degree of the cementing material is improved by adopting a hydrothermal-CO2 composite curing process, the strength is enhanced and the water absorption rate is reduced by fixing CO2, and meanwhile, environmental benefits are achieved.
本发明公开了一种基于多源工业废料的冷固结人工骨料及其制备方法，所述冷固结人工骨料包括质量份数如下的组分：高炉矿渣100‑200份、粉煤灰300‑400份、电石渣50‑450份、碱激发剂4‑60份、煤矸石25‑75份、水100份，其中，碱激发剂包括水玻璃和NaOH，分别占总质量份数的2‑30份和2‑30份。本发明通过圆盘成球工艺提高了骨料的核壳结构完整性，并通过表面预处理增强了附着力，提高了骨料的整体强度并降低了吸水率；通过物理‑化学‑内部三级联合活化处理工业废料，提高了活性和耐久性；采用水热‑CO2复合养护工艺提高了胶凝材料水化程度，并通过固定CO2增强了强度并降低了吸水率，同时具有环境效益。
