| titleOfInvention | A kind of recycled concrete and preparation method thereof |
| abstract | The invention discloses a recycled concrete and a preparation method thereof. The preparation method comprises the following steps: S1. crushing waste and old concrete and heating it; S2. separating the waste and old concrete treated in step S1. with slurry to obtain aggregate and cement slurry; S3. grinding and carbonizing the cement slurry obtained in step S2. to obtain regenerated cement; S4. sieving the aggregate obtained in step S2. and performing high-temperature carbonization treatment to obtain regenerated aggregate; S5. Mix the recycled cement obtained in step S3., natural river sand, the recycled aggregate obtained in step S4., an admixture and water to obtain the recycled concrete. The preparation method provided by the invention can recycle the aggregate and cement slurry in the waste concrete, the obtained recycled concrete has good performance, can effectively improve the utilization rate of construction waste resources, reduce the carbon emission, and alleviate the problem to a certain extent. The climate problem of global warming can also release the space occupied by construction waste and save valuable land resources. |
