Abstract

Abstract: As an important approach of resource utilization of industrial solid waste, sintered ceramsite not only has significant advantages in the heavy metal solidification, but also reduces the consumption of non-renewable resources such as clay and shale, making it a highly promising method for the resource utilization and harmless utilization of solid waste. In this paper, the solidification mechanism of heavy metals, the solidification effect (the solidification efficiency usually exceeds 80%), the application of ceramsite and the factors affecting the solidification effect of heavy metals and the product performance of ceramsite (bulk density, mechanical strength and water absorption) are systematically reviewed. Moreover, the current problems in the research of solid waste-based ceramsites and the possible research trends in the future are proposed, aiming to provide a scientific foundation for further improving the solidification efficiency of heavy metals and the ceramsite product performance of ceramsite sintered at high temperature.

Key words: solid waste utilization, ceramsite, heavy metal, solidification effect, product performance, solidification mechanism, application
