| Abstract: | To solve the disposal problem of hazardous waste oily sludge,a high sludge doping sintered ceramsite which used oily sludge as raw material,loess,sand and clay as additives was prepared.The maximum content and the best conditions were tested by single factor experiment.The microstructure,phase composition and element distribution in the inner and outer layers of the ceramsite were investigated by scanning electron microscopy (SEM),X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS).Results show that when the sludge content is 60% (mass fraction),the sintering temperature is 1 140 ℃,and the sintering time is 20 min,the target ceramsite with low water absorption and high compressive strength is obtained.Based on GB/T 17431.1—2010 "Light weight aggregate and its test methods",the ceramsite 1 h water absorption is 0.32%,the bulk density is 1 020.3 kg/m3 and the barrel pressure strength is 40.992 MPa under the best conditions. |
