Aggregates are classified by particle size and consistency. They can be subdivided into the categories: natural stone aggregates (sand and gravel) and crushed aggregates (stone chippings and crushed stones). Aggregates are generally available in the form of a homogeneous bulk product. The product characteristics are standardized, in order to ensure the necessary levels of reliability and processability.

Aggregates are used in a variety of industries for a range of purposes. They are a primary component in the production of concrete and asphalt, but also serve as a filter and fill material or as a basic material for road building and railway construction. Our product portfolio varies from country to country.

Development of sales volumes

In 2017, aggregates sales volumes rose by 12.2% to 305.3 million tonnes (previous year: 272.0). The high growth rate was largely due to the new markets in France, Italy, Spain, Greece, Morocco, Thailand, and North America, which were added from 1 July 2016, as well as to the full consolidation of the Koncrex International. On a pro forma basis and excluding the consolidation effects resulting from the expansion of our activities in North America and the full consolidation of Koncrex International in 2017, aggregates sales volumes were slightly above the previous year’s level with an increase of 1.1%.

Development in individual Group areas was rather mixed. The most substantial increase in deliveries was recorded in the Africa-Eastern Mediterranean Basin and Asia-Pacific Group areas and, to a lesser extent, in the Northern and Eastern Europe-Central Asia area. While sales volumes in North America almost reached the previous year’s level, they fell slightly in Western and Southern Europe.

Almost 50 years of company history have forged our identity, honored by everyone on our team. icon action
