| description | The invention belongs to the technical field of concrete for building materials, and particularly relates to a method for preparing recycled aggregate concrete from building waste, which comprises the following steps: S1, sorting the building waste; s2, the residual construction waste after sorting is put into a crusher to be crushed and screened, and the crushed mixture is put into washing equipment through a closed pipeline to be washed and screened; s3, aggregate formed by screening in S2 is collected and washed with water again, and recycled aggregate can be formed after drying in the shade; mixing and stirring the prepared recycled aggregate with a water reducing agent, broken stone, cement, water, quartz sand and powder to prepare the recycled aggregate concrete. The washing equipment comprises a body and a screening roller; the crushed construction waste mixture is put into the washing equipment, powder in the mixture is mixed with water to form slurry, the slurry flows out, flying dust pollution in th |
