The shale in the southeastern region of Chongqing is very rich.By taking the Longmaxi Formation shale from Nanchuan to Pengshui as the research object.The experimental plan for preparing shale ceramic particles in the region has been determined.Based on XRD analysis,the mineral phase characteristics of expansive shale and ceramsite were studied.The calcination system of shale ceramic particles in the study area was determined through orthogonal experiments.And single factor control was applied to different calcination parameters.Optimized the calcination mechanism for preparing ceramic particles from shale in the region.Intended to provide experimental basis and theoretical value for the preparation of shale ceramic particles in the southeastern region of Chongqing.Provide application reference for the subsequent large-scale application of ceramic particles as a multifunctional building material.
