Freeze resistance tests

The Freeze - Thaw test chamber was designed to meet the NFP18-425 standard (cycles of freezing in air and thawing in water) in order to determine the freeze resistance of hardened concrete :

  • "freeze-thaw" cycle of about 6h
  • samples freezing up to -18°C (probe inside one sample)
  • thawing at +9°C by samples immersion
  • unlimited cycles number

The great flexibility of the control software enables you to adapt the chamber to various freeze resistance tests.

The chamber can be used without the samples cabinet, for standardizes tests from -40°C to +90°C.

Features

The chamber is built to function in a dusty environment.

 

The samples cabinet is equipped with casters. Rails are laid inside the chamber to guide the cabinet when when loading and unloading. These operations are eased by a handling trolley specially designed to be locked on the chamber and supplied as standard.

The samples cabinet is supplied by an external water tank, which os regulated at the test temperature by a conditioning group.

Functioning principles :

The samples cabinet, placed inside the chamber, is conditioned in temperature in order to realize "freeze-thaw" cycles according to the standard to carry out.
The samples temperature is measured by a probe, drowned inside a concrete sample.
