Fair-faced concrete produced from construction waste recycled aggregate and preparation method of fair-faced concrete
The invention discloses fair-faced concrete produced from construction waste recycled aggregate and a preparation method of the fair-faced concrete. The fair-faced concrete produced from the construction waste recycled aggregate comprises the following components: recycled fine aggregate, sand, gravel, cement, fly ash, water, a naphthalene water reducer, dodecyl hydroxypropyl phosphate betaine, waterborne acrylic resin and a defoaming agent. The preparation method of the fair-faced concrete produced from the construction waste recycled aggregate comprises the following steps: modifying the recycled fine aggregate, adding the modified recycled fine aggregate, the sand, the gravel, the cement and the fly ash into a stirring pot, uniformly stirring, uniformly mixing the naphthalene water reducer, the defoaming agent, the water-based acrylic resin and the water, pouring into the stirring pot, and finally, adding dodecyl hydroxypropyl phosphate betaine, and uniformly stirring to obtain the fair-faced concrete produced from the construction waste recycled aggregate. The method has the effect of improving the compressive strength of the fair-faced concrete produced from the construction waste recycled aggregate.
本发明公开了一种建筑垃圾再生骨料生产的清水混凝土及其制备方法，一种建筑垃圾再生骨料生产的清水混凝土包括如下组分：再生细骨料、砂、碎石、水泥、粉煤灰、水、萘系减水剂、十二烷基羟丙基磷酸酯甜菜碱、水性丙烯酸树脂和消泡剂。一种建筑垃圾再生骨料生产的清水混凝土的制备方法为：先对再生细骨料进行改性，再将改性再生细骨料、砂、碎石、水泥和粉煤灰加入搅拌锅中搅拌均匀，再将萘系减水剂、消泡剂、水性丙烯酸树脂和水混合均匀后倒入搅拌锅，最后加入十二烷基羟丙基磷酸酯甜菜碱搅拌均匀得到一种建筑垃圾再生骨料生产的清水混凝土。本申请具有建筑垃圾再生骨料生产的清水混凝土的抗压强度的效果。
