Abstract
In order to recycle the waste concrete from which the reproductive aggregate should be produced in-situ, the applicability of crushers and recycled aggregates, and the compliance with the specification have been evaluated comprehensively. As a result of them, the properties of recycled aggregate particles were inferior to the natural one because of the adherent mortars on the recycled one, and the mobile impact crusher and the eccentric-mounted cone and jaw were superior to the others for the graded aggregates. In the case of anti-frost layer, the recycled one was easily controlled since the dry densities, contrary to natural one, were not largely changed with the moisture contents. It was found that the lean concrete base course is not influenced by absorption as cement dust grows larger, and the 7-day compressive strengths of lean concrete were higher than 10 MPa regardless of the crushing type.
