All-solid waste polymerized light soil suitable for large-volume pouring as well as preparation method and use method of all-solid waste polymerized light soil

The invention discloses all-solid-waste polymerized light soil suitable for large-volume pouring as well as a preparation method and a use method of the all-solid-waste polymerized light soil, and relates to the field of building materials and solid waste utilization. The all-solid waste polymerized light soil suitable for large-volume pouring comprises the following components in parts by weight: 30-60 parts of fly ash, 10-20 parts of slag powder, 10-20 parts of steel slag micro powder, 5-20 parts of caustic soda waste residues, 5-15 parts of soda ash waste residues and 0.02-0.2 part of a foaming agent. Wherein the main mineral phase components of the soda ash waste residue are calcium carbonate, calcium sulfate and calcium chloride, and the main mineral phase components of the caustic soda waste residue are rock salt, mirabilite and caustic soda; the sum of the parts by weight of the fly ash, the slag powder, the steel slag micro-powder, the caustic soda waste residues and the soda ash waste residues is 100
