Abstract:
Existing construction waste recycling and standards have long been applied in construction and demolition waste recycling. However, they have been essentially focused on the production and use of coarse recycled aggregates. This paper presents a technology that permits the production of high quality recycled sand. The selective removal with a vertical impact crusher of the cement paste attached to recycled aggregates and the potential improvements in the quality of the recycled sand that is produced were investigated. The results showed that the proposed method permitted the production of low-porosity sand from construction and demolition waste and may contributes to changing the construction recycling model.
