The invention discloses a high-strength concrete regeneration process which comprises the following steps: S1, pretreatment: crushing waste concrete blocks and removing reinforcing steel bars in the waste concrete blocks; s2, impurity removal is conducted, specifically, the concrete blocks obtained in S1 are placed in a water tank to remove adhered light impurities, and metal chippings in the concrete blocks are adsorbed and removed; s3, screening is conducted, specifically, the concrete blocks are screened through a screening machine, and the concrete blocks which do not meet the requirements return to S1 to be crushed; s4, drying: drying the concrete blocks obtained by screening in S3; s5, mixing and stirring: mixing and stirring the concrete blocks obtained in S4 with stones, medium sand, cement and mixing water to obtain recycled concrete, and placing the concrete blocks in a water tank to remove light impurities and metal chips, so that the impurities doped on the concrete blocks are reduced, the cleanliness of the concrete blocks is effectively improved, and the service life of the concrete blocks is prolonged. And the production quality of subsequent concrete is effectively improved.
本发明公开了高强度混凝土再生工艺，包括以下步骤，S1，预处理，对废弃混凝土块进行破碎并将其中钢筋进行去除；S2，杂质去除，将S1中得到混凝土块置于水箱中去除粘附的轻质杂质，并对混凝土块中的金属碎屑进行吸附去除；S3，筛分，将混凝土块通过筛分机进行筛分，不符合的混凝土块重新回到S1中进行破碎；S4，烘干，对S3中筛分得到的混凝土块进行烘干干燥；S5，混料搅拌，将S4中得到的混凝土块与石子、中砂、水泥、拌合水混合并搅拌，得到再生混凝土，通过将混凝土块置于水箱内进行轻质杂质以及金属碎屑的去除，减少混凝土块上所掺杂的杂质，有效提高混凝土块的干净度，进而有效提高后续混凝土的生产质量。
