Recycled concrete prepared from building wastes and preparation method of recycled concrete
The invention relates to the field of concrete, and particularly discloses recycled concrete prepared from building waste and a preparation method of the recycled concrete. The invention relates to recycled concrete prepared from building wastes, which is prepared from a concrete mixture and is prepared from water, cement, fly ash, recycled aggregate, natural aggregate, spinel powder, sodium methylene dinaphthalene sulfonate, sodium lignin sulfonate, sulfonated melamine formaldehyde resin, ferric trichloride and a retarder, the preparation method comprises the following steps: 1) uniformly mixing recycled aggregate, spinel powder and ferric trichloride to obtain a recycled aggregate mixture; 2) uniformly mixing water, cement, fly ash, sodium methylene dinaphthalene sulfonate, calcium lignosulphonate, sulfonated melamine formaldehyde resin and a retarder to obtain cement slurry; 3) adding a natural aggregate and recycled aggregate mixture into the cement slurry, and uniformly mixing to obtain a concrete mixture, and 4) pouring, curing and demolding to obtain the recycled concrete using the building waste. The method has the advantage of better reducing environmental pollution.
本发明涉及混凝土领域，具体公开了一种利用建筑废料的再生混凝土及其制备方法。一种利用建筑废料的再生混凝土，由混凝土拌和料制成，包括：水、水泥、粉煤灰、再生骨料、天然骨料、尖晶石粉末、亚甲基二萘磺酸钠、木质素磺酸钠、磺化三聚氰胺甲醛树脂、三氯化铁、缓凝剂，制备方法包括：1）再生骨料、尖晶石粉末、三氯化铁混合均匀得再生骨料混合物，2）水、水泥、粉煤灰、亚甲基二萘磺酸钠、木质素磺酸钙、磺化三聚氰胺甲醛树脂、缓凝剂混合均匀得水泥浆液；3）水泥浆液中投入天然骨料、再生骨料混合物，混合均匀，获得混凝土拌和料；4）浇筑，养护，脱模，得利用建筑废料的再生混凝土。本发明具有更好地降低环境污染的优点。
