DurabilityIndicators

The Tests

Gas permeability Measuring the flow of gas passing through a test specimen under constant pressure

Porosity, accessible to water Measuring the percentage of voids connected with the surface within the concrete mass

chlorides diffusion coefficient Measuring the amount of chloride penetration after a fixed period

The Durability of Concrete

Chemical Tests

GEOS performs the RCM test and steady diffusion test to determine chloride migration

GEOS determines the resistance to carbonation

Examination of the freeze-thaw resistance of concrete. This test can be performed with / without de-icing salts.

Petrographic Analysis

The Tests

Petrographic examination: • fast and reliable • determines the causes of damage • measures the extent of damage

Evaluating the parameters: • Damage caused by freezing or chemical

corrosion • Cause of cracks • Extent of the corrosion of the armature • Presence of fly ash, slag, ... • Sensitivity of aggregates to RAS

Petrographic examination gives a clear picture of potentially damaging phenomena in concrete

Microscopic AnalysisTests

To check the alkali-reaction phenomenon we perform a microscopic and physical examination on mixtures of concrete and aggregates.

Complementary Analysis

Tests

Chemical and mineralogical characterization by XRD analysis combined with EMS (Electron Microscope Scanner) provide in-depth information on the properties of materials.
