Concrete containing recycled aggregate and preparation method thereof
The invention relates to the technical field of concrete materials, and particularly discloses concrete containing recycled aggregate and a preparation method of the concrete. The concrete containing the recycled aggregate is prepared from the following components: water, cement, fly ash, natural fine aggregate, recycled coarse aggregate, a water reducing agent, a retarder, trimethylglycine, hyaluronic acid and aloe gel freeze-dried powder. The preparation method comprises the following steps: 1) uniformly mixing water, a water reducing agent, a retarder, trimethylglycine, hyaluronic acid and aloe gel freeze-dried powder to obtain a composite solvent; 2) adding cement and fly ash into the composite solvent, and uniformly mixing to obtain cement slurry; 3) adding the natural fine aggregate and the recycled coarse aggregate into the cement slurry, and uniformly mixing to obtain a concrete mixture, and 4) injecting the concrete mixture into a mold, and maintaining and curing to obtain the concrete containing the recycled aggregate. The method has the advantages that the doping amount of the recycled aggregate is increased, and the concrete is kept to have good performance.
本发明涉及混凝土材料技术领域，具体公开了一种含有再生骨料的混凝土及其制备方法。含有再生骨料的混凝土，包括以下组分：水、水泥、粉煤灰、天然细骨料、再生粗骨料、减水剂、缓凝剂、三甲基甘氨酸、玻尿酸、芦荟凝胶冻干粉。制备方法包括以下步骤：步骤1），将水、减水剂、缓凝剂、三甲基甘氨酸、玻尿酸、芦荟凝胶冻干粉混匀，得复合溶剂；步骤2），向复合溶剂中加入水泥、粉煤灰，混匀，得水泥浆液；步骤3），向水泥浆液中加入天然细骨料、再生粗骨料，混匀，得混凝土拌和料；步骤4），将混凝土拌和料注入模具中，养护、固化，得含有再生骨料的混凝土。本发明具有增大再生骨料的掺用量并保持混凝土具有较好的性能的优点。
