Sludge-based flow pouring type aerated unfired ceramsite lightweight aggregate and preparation method thereof
The invention discloses a sludge-based flow pouring type aerated unfired ceramsite lightweight aggregate and a preparation method thereof. The unfired ceramsite lightweight aggregate is prepared from the following raw materials: dewatered cement cakes, cement, a soil stabilizer, an exciting agent, a foaming agent and water. The weight percentage of each component in the solid raw material meets the following conditions: 20-50% of dewatered cement cake, 40-70% of cement, and 5-10% of # imgabs0 # exciting agent of which the soil stabilizer is the mass of the cement; the addition amount of the air bubbles is 100-300% of the total volume of the solid raw materials. The invention aims to utilize river and lake sludge dewatered cement cakes to replace natural clay to prepare the ceramsite, so that a large amount of oxides in the sludge are fully utilized, and pollutants in the sludge are solidified; meanwhile, in order to overcome the defect of high density of the unfired ceramsite, air bubbles are introduced, so that a honeycomb-shaped pore structure is formed in the unfired ceramsite, and the density of the ceramsite is reduced.
本发明公开了一种淤泥基流动浇筑型加气免烧陶粒轻集料及其制备方法，所述免烧陶粒轻集料的制备原料包括：脱水泥饼、水泥、土壤固化剂、激发剂、发泡剂和水；固体原料中各组分的重量百分比满足以下条件：脱水泥饼20～50％，水泥40～70％，土壤固化剂为水泥质量的#imgabs0#激发剂5～10％；空气泡的加入量为固体原料总体积的100～300％。本发明旨在利用河湖淤泥脱水泥饼代替天然粘土制备陶粒，以充分利用淤泥中的大量氧化物，并固化淤泥中的污染物；同时为解决免烧陶粒密度大的缺点，引入空气泡使免烧陶粒内部形成蜂窝状孔隙结构以减轻陶粒密度。
