Sludge unfired ceramsite as well as preparation method and application thereof
The invention belongs to the technical field of building materials, and particularly discloses sludge unfired ceramsite and a preparation method and application thereof.The sludge unfired ceramsite is of a three-layer sandwich core-shell structure, an inner core layer is prepared from sludge, biochar, cement, silica fume, fly ash, water glass, gypsum, rubber powder and glass beads, a middle layer is cement slurry, and the inner core layer is made of water; the shell layer is prepared from the following raw material components: sludge, cement, silica fume, fly ash, water glass and gypsum. According to the invention, sludge and cement are used as main raw materials, and a certain amount of water glass, gypsum, glass beads and solid waste silica fume and fly ash are used as auxiliary materials; the unfired ceramic particles are prepared by fully utilizing the sludge, the fly ash and the rubber powder as well as the specific biochar and the rubber powder, optimizing and reasonably compounding the raw materials and constructing a three-layer sandwich core-shell structure, and the light weight, low water absorption and high barrel pressure strength of the ceramsite are realized on the premise of ensuring high sludge utilization rate.
本发明属于建筑材料技术领域，具体公开了一种污泥免烧陶粒及其制备方法与应用，该污泥免烧陶粒具有三层夹心核壳结构，其中：内核层的原料组分包括污泥、生物炭、水泥、硅灰、粉煤灰、水玻璃、石膏、橡胶粉和玻璃微珠，中间层为水泥浆料，外壳层的原料组分包括污泥、水泥、硅灰、粉煤灰、水玻璃和石膏。本发明以污泥和水泥为主要原料，同时配以一定量的水玻璃、石膏、玻璃微珠和固体废弃物硅灰、粉煤灰；以及特定的生物炭和橡胶粉，充分利用固体废弃物污泥、粉煤灰和橡胶粉，通过对各原料进行优选、合理复配并构建三层夹心核壳结构，制备了免烧陶瓷粒，在保证较高污泥利用率的前提下，实现了陶粒的轻质化、低吸水率和高桶压强度。
