| Abstract: | This aticle studies the high-strength ceramisite which prepared by bayer red mud,shale and fly ash.The highest content of red mud is 50 %.The result is that：bulk density of ceramisite is 840 kg/m3,cylindrical compress strength is 7.5 MPa,the strength is 45 MPa,water absorption is 6.9 %,apparent density is 1000 kg/m3,porosity is 16.0 %,and the radioactive of the ceramistie can meet the requirement of lightweight aggregate.In addition,analyses the sintering mechanism of red mud ceramisite by the XRD,SEM and other methods. |
