This invention belongs to the field of building materials technology and specifically relates to a concrete sulfate crystallization damage inhibition material. It consists of an air entraining agent, a water reducer, and one or more active admixtures. The water reducer can be one or more of lignosulfonate, poly(e-methylnaphthalene sulfonate), melamine-formaldehyde condensation polymer, or polycarboxylate water reducer; the air entraining agent can be one or more of triterpenoid saponin surfactants, sodium salts of rosin resin compounds, fatty acid salt compounds, sulfonated hydrocarbons, or alkyl-benzyl sulfonate compounds; the active admixture can be one or more of fly ash, slag micro powder, silica fume, or coal gangue powder. By incorporating this invention into concrete, it can significantly reduce the expansion rate caused by concrete sulfate crystallization, greatly decrease the amount of concrete peeling and strength loss caused by salt crystallization, and significantly enhance the concrete's resistance to sulfate crystallization damage. The production process of this invention is simple, the price is cheap, and it is also easy to promote and apply.
