Thin-section analysis brings hard facts on structural conditions
The investigations of the condition of and potential damage in old concrete structures,
the selection of the correct type and extent of repairs, and
ensuring a sufficient service life all require information on the
microstructure of concrete.
A versatile tool in the investigations of the microstructure of concrete is so-called
thin-section analysis, which allows us to detect damage that has
started in a structure, but which is still outwardly invisible. In
new building projects, thin-section analysis makes quality assurance
more reliable.
Microscopic analysis of a thin-section from a concrete sample
can reveal, for instance:
Carbonation (risk of steel corrosion)
Air
void structure (frost resistance)
Types
of fracture (causes of damage)
Other
hidden risks of damage (e.g. pore fillers).
Thin-section analysis
can be used to investigate the microstructure of samples of not only
concrete, but also of mortar, stones, paint and coating surfaces,
bricks, ceramic tiles, and other building materials.
