Recycled concrete
The invention belongs to the technical field of concrete, and particularly relates to recycled concrete which is prepared from the following components in parts by weight: 1000 to 1200 parts of modified recycled coarse aggregate, 500 to 600 parts of sand, 430 to 530 parts of cement, 600 to 750 parts of fly ash, 20 to 25 parts of water reducing agent and 150 to 250 parts of water. According to the recycled concrete disclosed by the invention, all the used coarse aggregates are recycled coarse aggregates, and the recycled coarse aggregates are modified before being added, so that the strength of the recycled coarse aggregates and the interface bonding force between the recycled coarse aggregates and other components are improved, and the recycled concrete with high strength, good durability and good crack resistance is obtained.
本申请属于混凝土技术领域，具体涉及一种再生混凝土，包括如下重量份的各组分：改性再生粗骨料1000‑1200份、砂500‑600份、水泥430‑530份、粉煤灰600‑750份、减水剂20‑25份、水150‑250份。本申请的再生混凝土，所用的粗骨料全部为再生粗骨料，并在添加前先对再生粗骨料进行改性，提高再生粗骨料的强度以及再生粗骨料与其他组分之间的界面结合力，从而获得强度高、耐久性好、抗裂性好的再生混凝土。
