The invention discloses concrete taking industrial waste residues as an admixture and a preparation method thereof. The concrete taking industrial waste residues as an admixture is prepared from the following raw materials in parts by weight: 265-285 parts of cement, 360-400 parts of river sand, 940-970 parts of stones, 160-200 parts of water, 45-55 parts of fly ash, 45-70 parts of slag powder, 380-410 parts of artificial sand, 8-10 parts of an additive and 100-185 parts of modified phosphorus slag powder. The modified phosphorus slag powder comprises the following components: phosphorus slag,a grinding aid, stearic acid, a water reducing agent, water, water glass, aluminum potassium sulfate, sodium sulfate, polyacrylamide, carboxymethyl cellulose, coal gangue and gypsum. The concrete taking industrial waste residues as an admixture has the advantages that the setting time is short, the early strength is high, nitric oxide in automobile exhaust can be adsorbed and degraded, industrialsolid waste is utilized, environmental protection is facilitated, and waste is turned into wealth.
