Aggregates
Aggregates are natural or crushed materials that, when mixed with binders like cement, lime, or asphalt, do not actively contribute to the setting and hardening process. Instead, they play a vital role in enhancing the mechanical strength of the final product by bonding together.
As a subsidiary of HERACLES Group, Lafarge operates 10 limestone quarries dedicated to the extraction and production of high-quality aggregates. Our products undergo rigorous quality control in state-of-the-art laboratories, ensuring full compliance with European standards (EN STANDARDS).
Aggregates
- Concrete aggregates - Asphalt mix materials - Mortar aggregates
- Road construction materials - Backfilling
- Specialty Aggregates
The main Aggregate quarries of HERACLES Group
The aggregate quarry at "Κεραμιδέζα" in Mandra, Attica, began operations in 1981 and has been part of HERACLES Group since 2022. It is one of the largest quarries in Europe, with an annual production capacity exceeding 4,000,000 tons.
Products: Concrete aggregates, asphalt and mortar aggregates (also available in Big Bags), graded road construction and backfill aggregates, and specialty application aggregates.
The aggregate quarry in Mesaio, Thessaloniki, began operations in 1977 and has been part of HERACLES Group since 2005. It is one of the largest limestone aggregate quarries in Northern Greece.
Products: Concrete aggregates, asphalt and mortar aggregates, graded road construction and backfill aggregates, and specialty application aggregates.
The aggregate quarry at "Mavra Vouna" in the municipal district of Araxos, Achaia, began operations in 1994 and has been part of HERACLES Group since 1999. It was the exclusive supplier for the Rio-Antirrio Bridge project, delivering a total of 750,000 tons of high-spec aggregates.
Despite being one of HERACLES Group’s oldest quarries, strategic investments over the past decade have transformed it into one of the most advanced quarries in Greece.
Products: Concrete aggregates, asphalt and mortar aggregates, graded road construction and backfill aggregates
Aggregate Fractions
Following the stage of their extraction, the aggregates pass through special crushers, where their size is reduced and then they are separated accordingly.
This provides the three basic sizes (fractions) of aggregates used in concrete:
Sand (0-4mm)
Fine aggregate (4-16mm)
Gravel (16-32mm)
For higher or equivalent categories of concrete with C20 / 25, three fractions are required (CTS - 97).
There are other sizes of aggregates for more specialised uses such as:
“Rice” (4-8mm)
Coarse gravel (32-64mm)
