Geopolymer core-shell structure lightweight aggregate and preparation method thereof
The invention discloses a geopolymer core-shell structure lightweight aggregate and a preparation method thereof. The method comprises the following steps: preparing slag, silica fume, fly ash, gypsum and instant sodium silicate into a calcined clay-based green and environment-friendly cementing material in proportion; putting the core material particles into a lightweight aggregate granulation device, then putting a calcined clay-based green environment-friendly cementing material, pouring the quick lime slurry, and meanwhile, pouring a mixing agent for granulation to form a primary cold-bonded aggregate; a curing process combining natural curing (12h), moisturizing curing (12h) and steam curing (12h) is adopted for the primary cold-bonded aggregate. According to the slag-based core-shell structure lightweight aggregate and the preparation method thereof, the slag-based core-shell structure lightweight aggregate is energy-saving, low in consumption, low in cost, capable of saving natural resources, simplified in processing flow, capable of realizing solid waste recycling, low in water absorption rate and high in single particle bearing capacity.
本发明公开了一种地聚物核壳结构轻骨料及其制备方法，方法包括：将矿渣、硅灰、粉煤灰、石膏、速溶硅酸钠按比例配置成煅烧粘土基绿色环保胶凝材料；将内核材料颗粒放进轻骨料造粒装置内，然后投放煅烧粘土基绿色环保胶凝材料，倒入生石灰浆体，同时倒入混合剂进行造粒，形成初生冷粘骨料；对初生冷粘骨料采用自然养护(12h)‑保湿养护(12h)‑蒸汽养护(12h)相结合的养护工艺。本发明是一种节能低耗、低成本、节约自然资源、简化加工流程且能实现固废资源化的、吸水率低且单颗承载力高的矿渣基核壳结构轻骨料及其制备方法。
