Aggregates are materials of rocky origin, extracted from river deposits such as natural sand, gravel and crushed stone or crushed by hard rock formations.
Crushed aggregates are mixed with hydraulic binders such as cement to obtain concrete, mortars and plasters. They are also used as such for other engineering works such as roads and foundations for other structures.
Aggregates provide better fluidity in ready-mix concrete production and improve its mechanical properties, to counteract plastic mass shrinkage and reduce hydration heat.
Through crushing, shaping, shielding and washing processes, aggregates can be processed to obtain products of different sizes and characteristics, which can be divided into sands, intermediate aggregates and large aggregates.
Thanks to its ample material reserves in Denmark, Sweden and Belgium, Cementir group is one of the most important aggregate operators in these countries. Since 2021 Cementir has entered the Aggregates business also in Türkiye, with the acquisition of EGE Kirmatas, in the Aegean region.

Production process
TRANSCRIPT - PRODUCTION PROCESS
Stage 1: Quarrying
This stage covers the preparation and extraction of rock from the quarry:
Overburden: Removal and management of the topsoil/waste layers.
Backfill & Quarry Rehabilitation: Refilling and replanting trees for environmental restoration.
Drilling: Performed on the hard rock layer.
Blasting: Using explosives to break up the rock.
Loading: Picking up the blasted rock.
Hauling: Transporting the material to the crusher.
Stage 2: Crushing & Screening
The raw material is processed into various sizes:
Input: Material arrives from the quarry and enters the Hopper.
Grizzly Feeder: Separates the flow; some material goes to Bypass, the rest to crushing.
Primary Crusher: Gyratory or jaw type.
Screen: First separation stage leading to initial piles.
Belt Conveyor: Moves material to the next processing units.
Secondary Crusher: Further reduces the rock size.
Screen: Produces Product Piles (Coarse).
Tertiary Crusher: Final reduction stage (via belt system).
Screen: Produces Fine & Sand piles.
Loading Dispatch to Customers: Finished products are loaded onto trucks for delivery.
