End of life recycling - concretecentre

The constituents of concrete can be recycled materials, and concrete itself can also be recycled; these materials are usually available locally. Concrete pieces from demolished structures can also be reused to protect shorelines, for example in gabion walls or as rip rap.

Recycling concrete: processes and benefits - Sustaining ...

14/03/2019  The processes of recycling concrete A paddle crusher converts deteriorated barriers into one-inch bits. A paddle wheel inside spins and crushes the concrete, and afterward, the pieces are moved to a vibrating sorting box. These pieces of a once massive concrete slab are then recycled in roadwork, erosion, and dust control projects.

Ability of recycling on fiber reinforced concrete ...

30/09/2014  Fiber Reinforced Concrete (FRC) can improve not only mechanical properties but also durability due to reduced crack width. Previous researches only enhance the advantages of fiber addition. From the view point of sustainability, the treatment of FRC after the service period of concrete structures should be one of the important issues in near future. This paper presents the ability of recycling ...

Contamination Problems in the Recycling of Concrete ...

Abstract. Concrete rubble has the possibility of being contaminated by a variety of foreign materials. The presence of contaminants should be considered when old concrete is to be incorporated into new, and an assessment made of their potential undesirable interactions, if any, under the anticipated service conditions of the new concrete.

Recycling and reuse - SteelConstructionfo

Importantly, the majority of the construction and demolition arisings are heavy bulk wastes such as concrete, masonry and asphalt which are generally crushed and downcycled into lower grade applications such as general fill. Although landfill is avoided, downcycling is low-grade recycling and low down on the UK waste hierarchy. More has to be done to encourage reuse and higher grade recycling ...
