Recycled aggregate concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses recycled aggregate concrete and a preparation method thereof. The recycled aggregate concrete is prepared from the followingraw materials in parts by weight: 270-290 parts of cement; 80-100 parts of fly ash; 780-810 parts of sand; 800-820 parts of modified recycled coarse aggregate; 180-200 parts of natural broken stone; 8-10 parts of an additive; 150-160 parts of water; the modified recycled coarse aggregate is composed of a core body and a coating film, the core body is the recycled coarse aggregate, and the coatingfilm is alkali-soluble resin; the preparation method comprises the following steps: weighing the raw materials in proportion; uniformly stirring and mixing natural gravel, sand, the modified recycledcoarse aggregate, cement and fly ash to obtain a first mixture; and uniformly mixing water and the additive, adding the mixture into the first mixture, and uniformly stirring to obtain the recycled aggregate concrete. The recycled aggregate concrete has the advantage of good fluidity; in addition, the preparation method has the advantages of being simple, efficient and suitable for large-scale production and use.
本申请涉及混凝土领域，具体公开了一种再生骨料混凝土及其制备方法。再生骨料混凝土由包含以下重量份的原料制成：水泥270‑290份；粉煤灰80‑100份；砂780‑810份；改性再生粗骨料800‑820份；天然碎石180‑200份；外加剂8‑10份；水150‑160份；所述改性再生粗骨料由核体和包覆膜构成，所述核体为再生粗骨料，所述包覆膜为碱溶性树脂；其制备方法为：按配比称取原料；将天然碎石、砂、改性再生粗骨料、水泥、粉煤灰搅拌混合均匀，得到第一混合物；将水和外加剂混合均匀后加入所述第一混合物中，搅拌均匀得到再生骨料混凝土。本申请的再生骨料混凝土具有流动性好的优点；另外，本申请的制备方法具有制备方法简单高效，适于大规模生产使用的优点。
