Ceramsite and preparation method thereof
The invention relates to the technical field of solid waste utilization, and provides ceramsite and a preparation method thereof. The ceramsite is composed of 80-100 parts by weight of engineering muck and 0-20 parts by weight of metakaolin. The main oxides of the engineering muck comprise SiO2, Al2O3 and Fe2O3, the content of SiO2 is larger than 50%, the content of Al2O3 is larger than 16%, and the content of Fe2O3 is smaller than 8%. The main oxide of metakaolin is SiO2, and the content of SiO2 is greater than 90%. The high-strength ceramsite is obtained by controlling the raw material composition and proportion of the ceramsite and utilizing the engineering residue soil in a large proportion, and environmental pollution is avoided while the engineering residue soil is recycled. In addition, the high-strength ceramsite provided by the invention can replace sandstone in a high-strength concrete product, so that the exploitation of sandstone resources is reduced, and the environment is protected.
本发明涉及固废利用技术领域，本发明提供了一种陶粒及其制备方法，该陶粒由80‑100重量份的工程渣土和0‑20重量份的偏高岭土组成，其中工程渣土的主要氧化物组成为SiO2、Al2O3和Fe2O3，SiO2含量＞50％、Al2O3含量＞16％、Fe2O3的含量＜8％；偏高岭土的主要氧化物组成为SiO2，且SiO2的含量＞90％。本发明通过控制陶粒的原料组成和配比，大比例地利用了工程渣土获得了高强度的陶粒，对工程渣土进行再利用的同时，也避免了环境的污染；此外，本发明提供的高强度陶粒可替代高强混凝土制品中的砂石，减少了砂石资源的开采，保护了环境。
