The invention discloses low-sintering-temperature light-weight high-strength shale ceramsite and a preparation method thereof, and relates to the technical field of artificial light aggregates for concrete.The method comprises the steps that shale powder serves as a main material, biomass powder serves as a pore-forming template, and one or more of waste glass powder, plant ash, red mud and fluorite are compounded to serve as a sintering aid, so that raw materials are formed; the preparation method comprises the following steps: weighing the raw materials according to the proportion, and homogenizing to obtain uniformly dispersed composite powder; preparing the composite powder into a ceramsite raw material by adopting a granulator, sintering the dried ceramsite raw material at high temperature in an inert atmosphere or a reducing atmosphere, and cooling along with a furnace after sintering to obtain the low-sintering-temperature light-weight high-strength shale ceramsite. The shale ceramsite is simple in preparation process, low in energy consumption, low in carbon emission and low in cost, and the prepared shale ceramsite has a compact surface glaze layer and a porous core structure and has the advantages of low density and high strength.
一种低烧结温度轻质高强页岩陶粒及其制备方法，涉及混凝土用人造轻集料技术领域，其中的方法包括以页岩粉体为主料，以生物质粉体为成孔模板，以废弃玻璃粉、草木灰、赤泥、萤石中的一种或多种复合使用为烧结助剂，从而形成原料；将所述原料按照配比称量后进行均化处理得到均匀分散的复合粉体；采用造粒机将复合粉体制备成陶粒生料，将干燥后的陶粒生料在惰性气氛或者还原性气氛下进行高温烧结，烧结完毕后随炉冷却，获得所述的低烧结温度轻质高强页岩陶粒。本发明制备工艺简单，能耗低、碳排放烧、成本低，制备出的页岩陶粒拥有致密的表面釉层和多孔芯部结构，具有低密度和高强度兼顾的优势。
