Magnesium slag unfired ceramsite and preparation method thereof
The invention provides magnesium slag non-sintered ceramsite and a preparation method thereof, and belongs to the technical field of ceramsite preparation. The magnesium slag non-sintered ceramsite provided by the invention is of a core-shell structure, and the fly ash is utilized as a raw material for preparing the ceramsite core and the ceramsite outer wall to provide silicon and aluminum elements, and the silicon and aluminum elements are used as main active components for forming the ceramsite; the magnesium slag is used for providing silicon and calcium elements, and the utilization rate of industrial solid waste in ingredients is increased; according to the invention, gypsum is utilized to provide calcium element, hydration of active components in fly ash is promoted, and the strength of ceramsite is improved; by controlling the proportion of the raw materials, the magnesium slag non-sintered ceramsite obtained through curing can keep high mechanical performance and low stacking density. The compactness of the outer wall of the ceramsite is controlled to be higher than that of the core of the ceramsite, the outer wall of the unfired ceramsite forms a hard protective shell, the core of the ceramsite is protected, and the mechanical strength of the magnesium slag unfired ceramsite is improved; the ceramsite core has lower compactness, so that the magnesium slag unfired ceramsite has lower bulk density.
本发明提供了一种镁渣免烧陶粒及其制备方法，属于陶粒的制备技术领域。本发明提供的镁渣免烧陶粒为核壳结构，且制备陶粒核心和陶粒外壁的原料利用粉煤灰提供硅和铝元素，作为形成陶粒的主要活性成分；本发明利用镁渣提供硅和钙元素，增大配料中的工业固废利用率；本发明利用石膏提供钙元素，促进粉煤灰中活性组分的水化，提高陶粒的强度；本发明通过控制原料的配比，能够使养护得到的镁渣免烧陶粒保持较高的机械性能和较低的堆积密度。本发明通过控制陶粒外壁的密实度高于陶粒核心的密实度，免烧陶粒外壁形成坚硬的保护壳，保护陶粒核心，提高镁渣免烧陶粒的机械强度；陶粒核心较低的密实度，使得镁渣免烧陶粒具有较低的堆积密度。
