The invention relates to inorganic lightweight aggregate thermal mortar for a steel structure. The inorganic lightweight aggregate thermal mortar for the steel structure is composed of powder and lightweight aggregate, wherein the power is prepared from the components, in parts by mass: 500-900 parts of cement, 50-180 parts of coal ash, 10-60 parts of redispersible latex powder, 2.0-9.0 parts of cellulose ether, 40-100 parts of natural zeolite powder, 0.05-0.35 part of starch ether and 1.0-70 parts of fiber. The cement, coal ash and redispersible latex powder jointly form a compound binding material system; the cement provides the initial bonding strength through preliminary rapid hydration; the coal ash replaces part of the cement to serve as a binding material to achieve the function ofimproving the anti-permeability of mortar while improving the peaceability of mortar; redispersible latex powder is in contact with water to be emulsified to be a film, and film and a hydrated productof cement form an inter-p
