Concrete taking industrial waste residues as admixture and preparation method thereof
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.
本发明公开了一种以工业废弃残渣为掺合料的混凝土及其制备方法。以工业废弃残渣为掺合料的混凝土包括以下重量份的原料：265‑285份水泥、360‑400份河砂、940‑970份石子、160‑200份水、45‑55份粉煤灰、45‑70份矿渣粉、380‑410份人工砂、8‑10份外加剂、100‑185份改性磷渣粉；改性磷渣粉包括以下组分：磷渣、助磨剂、硬脂酸、减水剂、水、水玻璃、硫酸铝钾、硫酸钠、聚丙烯酰胺、羧甲基纤维素、煤矸石、石膏。本发明的以工业废弃残渣为掺合料的混凝土具有凝结时间短，早期强度高，能吸附并降解汽车尾气中氮氧化物，且利用工业固体废弃物，有利于环保，变废为宝的优点。
