| titleOfInvention | Recycled aggregate prepared from residual concrete in concrete mixer truck tank |
| abstract | The invention belongs to the technical field of building materials, and discloses a recycled aggregate prepared by utilizing residual concrete in a concrete mixer truck tank, which comprises the following components in percentage by mass: 84-93% of residual concrete, 1-3% of a coagulation accelerating component, 5-10% of a reinforcing component and 1-3% of a high water absorption polymer. The invention further discloses a preparation method of the recycled aggregate. By adopting the technical scheme of the invention, the residual concrete in the concrete mixer truck tank can be fully recycled, the granular recycled aggregate with excellent performance can be prepared in a short time, and meanwhile, the method is not influenced by the water cement ratio and the composition of the residual concrete in the concrete mixer truck tank, and can be used for preparing recycled aggregates by residual concrete with various grades. The crushing value, apparent density, water absorption and firmness of the recycled aggregate prepared by the method meet the I-type requirements of GB/T25177 recycled coarse aggregate for concrete, the residual concrete in the concrete mixer truck tank is utilized to the maximum extent, resources are saved, and the environment is protected. |
