Concrete aggregates properties crushed by jaw and impact secondary crushing
Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing March 14, 2023. 1. 8960. Crushing and Screening Equipment for Concrete Recycling. There are two approaches to recycling concrete. One approach is to haul the concrete debris to a permanent recycling facility or quarry for crushing and screening. The alternative is to crush and screen the material at the demolition site.Crushing and Screening Equipment for Concrete Recycling

Because of these hindrances, the market uptake of recycled aggregates (RA) by the concrete industry is quite limited. As presented in the 2019–2020 annual review of UEPG (the European Aggregates Association) [], only 10.6% of all aggregates produced in the EU + EFTA (the European Free Trade Association) were RA, most of which were 2.

Recommendations for the management of construction and demolition waste
Separating the different fractions using a selective demolition process can result in increased costs for demolition. To compensate for this, the CDW treatment plants must offer differentiated fees, depending on the CDW degree of contamination upon reception (Yuan 2017; Yuan et al. 20011).. Solís-Guzmán et al. proposed that the This study collected basic information and conducted waste composition surveys to identify the present management condition of construction and demolition waste (CDW) landfills in Hanoi of Vietnam and to characterize waste composition and grain size distribution of CDW dumped at landfills.

Recycled Aggregates Produced from Construction and Demolition Waste
This paper concerns the recovery of construction and demolition waste as coarse recycled aggregates for concrete. Coarse recycled aggregates may be used as a partial or total replacement of natural aggregates, contributing to the circular economy and minimizing landfill disposals as well as the consumption of natural mineral resources. The tested material was directly obtained from the waste plant after preliminary crushing, and the particle size of the CDW ranged from 9.5 to 26.5 mm. In this study, the aspect ratio was used to characterize the particle shape (Xiao et al., 2019). Two extreme conditions of particle shapes were.

Production of natural and recycled aggregates: the
Natural aggregates (NA) are crushed and processed in crushing plants after the extraction stage in quarries. In the present study, the aggregates are divided into three scenarios, depending on the production methods. The first scenario considers the production of NA, the second scenario deals with the production of recycled aggregates This study collected basic information and conducted waste composition surveys to identify the present management condition of construction and demolition waste (CDW) landfills in Hanoi of Vietnam and to characterize waste composition and grain size distribution of CDW dumped at landfills.
