Abstract: In order to promote the resource utilization and high-value utilization of bulk industrial solid waste，the comprehensive utilization of bulk industrial solid waste in the field of valuable metals and building materials was reviewed according to the status and characteristics of bulk industrial solid waste. The construction and sintering mechanism of new Si-Ca based ceramic system using industrial solid waste were analyzed. From the current stage of development，in-depth exploration of the feasibility and technical prospects of the research and development of Si-Ca-based foamed ceramic products，and the realization of the coordinated preparation of Si-Ca-based foamed ceramics from bulk industrial solid waste can not only eliminate a series of hidden dangers of solid waste storage，alleviate the environmental protection pressure of enterprises，ensure the sustainable development of mineral resources，but also save the exploitation and consumption of natural resources in the field of foamed ceramics，innovate the preparation process and technology，and help“carbon peak，carbon neutralization”.

Key words: industrial solid wastes, resource utilization, Si-Ca based ceramics, foamed ceramics
