Summary: | The invention discloses a high-strength ceramsite and a preparation process thereof. Wet mud powder obtained after filter pressing of mud and powder generated in the gravel aggregate processing process is directly used as a main raw material, small amounts of a pore-forming agent and a fluxing agent are added, kneading, granulation, preheating and high-temperature roasting are carried out to prepare the artificial light bone ceramsite, and the ceramsite is spherical and subsphaeroidal, is hard in skin, and fully filled with fine pores. The prepared ceramsite is high in density, high in strength, low in heat conductivity coefficient, high in refractoriness, good in chemical stability and non-toxic and harmless, the problem that aggregate processing garbage is difficult to treat can be solved, waste is turned into wealth, and good social benefits and environmental protection benefits are achieved.
