Preparation method of reinforced recycled aggregate concrete
The invention provides a preparation method of reinforced recycled aggregate concrete, which comprises the following specific steps: firstly, pre-treating waste concrete to remove small particles, dust and attached mortar, then mixing with epoxy resin and a water reducing agent, and finally adding polyacrylamide-coated copper powder, modified graphene and a silane coupling agent to prepare reinforced aggregate, thereby obtaining the reinforced recycled aggregate concrete. And mixing and stirring the reinforced aggregate, natural aggregate, cement, water and sand according to a certain proportion to prepare the reinforced recycled aggregate concrete.
本发明提供了一种强化再生骨料混凝土的制备方法，具体步骤为，首先将废弃混凝土经过前处理，去除较小的颗粒、灰尘和附着砂浆，再与环氧树脂和减水剂混合，最后加入聚丙烯酰胺包裹的铜粉、改性石墨烯、硅烷偶联剂，制得的强化骨料，再将强化骨料与天然骨料、水泥、水和沙按照一定比例混合搅拌制得强化再生骨料混凝土。
