High-quality regenerated aggregate as well as preparation method and application thereof
The invention discloses a high-quality regenerated aggregate and a preparation method and application thereof, and belongs to the technical field of regenerated aggregates, and the preparation method of the high-quality regenerated aggregate comprises the following steps: S1, high-temperature preheating treatment: heating the regenerated aggregate to 450 DEG C by adopting microwave heating; s2, carrying out rolling treatment on the regenerated aggregate, namely rolling and crushing the regenerated aggregate subjected to heat treatment by adopting a jaw crusher, sieving and grading to obtain the regenerated aggregate; s3, molding and grinding the recycled aggregate: putting the sieved and graded recycled aggregate into an eccentric grinding device for molding and grinding; s4, an activation strengthening process: soaking the regenerated aggregate in a self-made modification strengthening solution until the solution is completely and fully hung on the surface of the regenerated aggregate; and taking out and drying to obtain the high-quality regenerated aggregate. The ultra-high performance concrete prepared by adopting the high-quality recycled aggregate disclosed by the invention can have relatively excellent freeze-thaw resistance and durability.
本发明公开了一种高品质再生集料及其制备方法与应用，属于再生集料技术领域，所述高品质再生集料的制备包括以下步骤：S1、高温预加热处理，采用微波加热，将再生集料加热至450摄氏度；S2、轧制处理再生集料，采用鄂式破碎机轧制破碎热处理过后的再生集料，并过筛、分档得到再生集料；S3、造型修磨再生集料，将过筛、分档得到的再生骨料置于偏心研磨装置中进行造型修磨；S4、激活强化工艺，将再生集料置于自制改性强化液中浸泡，待再生集料表面全部充分挂液；取出后烘干，即制备得到高品质再生集料。采用本申请高品质再生集料制备得到的超高性能混凝土，能够具备较优异的抗冻融和耐久性能。
