Concrete, bricks and mortar are processed on site to produce the aggregate materials for use in new construction: G4, G5, G7, G9 and kerbmix. Although generally seen as ‘contaminants’ in an aggregate producing business, other materials delivered to site have subsequently generated income opportunities for the surrounding community.

Recycled Concrete Aggregate - an overview | ScienceDirect

Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete.

Trio® CT Series Jaw Crushers | Weir

Trio CT series jaw crushers combine a robust design with a steep nip angle and an optimised toggle. This results in a jaw crusher which offers a more aggressive bite and reliable operation, with life-cycle improvements of its mechanical and hydraulic parts. The CT series can also be fitted with a hydraulic toggle relief system as required.
