The invention belongs to the technical field of building materials, and particularly relates to a concrete sulfate crystallization destruction inhibition material. consists of an air-entraining agent, a water-reducing agent and an active admixture, wherein the water-reducing agent is one or more of lignosulfonate, e-methylnaphthalene sulfonate condensate, melamine formaldehyde condensate or polycarboxylate water-reducing agent; the air-entraining agent is one or more of triterpene saponin surfactants, rosin resin sodium salt compounds, fatty acid salt compounds, sulfonated hydrocarbons or alkyl-benzyl methanesulfonate compounds; The active admixture is one or more of fly ash, slag powder, silica fume or coal powder. When the invention is mixed into concrete, the expansion rate caused by sulfate crystallization of concrete can be significantly reduced, the spalling amount and strength loss of concrete caused by salt crystallization can be greatly reduced, and the resistance to sulfate crystallization damage of concrete can be significantly improved. The invention has simple production process, low price, and easy popularization and application.<o></o>
