Abstract

Abstract

To address the issue of resource waste caused by the storage of industrial waste residue from polyaluminum chloride， this study innovatively developed a process for preparing non-fired ceramic particles based on polyaluminum chloride slag. By systematically examining the effects of different factors on the performance of ceramic particles， combined with scanning electron microscopy （SEM） microstructure characterization and X-ray diffraction （XRD） phase analysis， the generation of the phases and its mechanism was observed. The results showed that the optimal water-cement ratio for the formation of non-fired ceramic particles from polyaluminum chloride slag was 0.24， the slag-cement ratio was 5∶5， the cement addition was 15%， the sodium silicate content was 9%， and the sodium hydroxide content was 11%； the cylindrical compressive strength of non-fired ceramic particles under this condition was 4.6 MPa， the bulk density was 795.8 kg/m³， and its water absorption capacity was 6.74%， which met the ceramic particle performance requirements in China’s national standard， Lightweight Aggregates and Their Experimental Methods （GB/T 17431.1—2010）. The microscopic analysis showed that the main phase of 28 day non-fired ceramic particles is quartz and gel. The gel bodies were connected and the pores were filled， to make the structure more compact. Preparatoin of the non-fired ceramic particles was with a total cost of approximately 288.46 yuan/m³ through calculation.
