Freeze-thaw testing

GEOS triples capacity for freeze-thaw tests

Due to high demand, our dedicated laboratory has tripled its capacity for freeze-thaw testing on ceramic building materials. The expansion of the laboratory in Wellen makes it possible to test three times more samples than before.

Freeze-thaw tests are used to assess the durability and resistance of materials to repeated freeze-thaw cycles. The purpose of this test is to evaluate how well a material can withstand the expansion and contraction caused by freezing and thawing. The applications in construction and transport infrastructure are numerous.

The requirements and test methods for baked building materials, such as bricks, are laid down in the European standards NBN EN 1344/AC and NBN EN 772-22(2019).
The expansion of GEOS’s freeze-thaw laboratory makes it possible to test all types of building materials, including:

  • Concrete products
  • Road concrete
  • Aggregates
  • Bricks
  • Natural stone

The tests can take between 2 weeks and 3 months, depending on the material and the desired test method.
The results of the freeze-thaw tests can be used by manufacturers to:

  • Better weigh the selection of materials
  • Customize the design of structures
  • To develop suitable construction techniques
  • Ensuring a longer service life
  • Minimize maintenance needs

The expansion of the freeze-thaw laboratory is another important step in the development of GEOS. It enables GEOS to provide faster service to its customers, helping manufacturers to continue optimizing their processes and supporting users to choose the most suitable materials for their projects, ensuring longer life and lower maintenance.
