Freeze-Thaw Durability Testing

We offer standardized freeze-thaw testing for routine quality assurance or custom-designed tests for durability studies or forensic evaluations.

No single mechanism is responsible for all types of freeze-thaw damage. The physics of freeze-thaw behavior depend on material types, pore structures, and exposures. It is not surprising that there is no single durability test that applies to all situations. Highbridge is equipped to provide solutions for your project requirements and can help you determine the right testing protocol.

Our diverse test offering include:

  • Saturation coefficient determination using absorption

  • ASTM C67 for brick and terra cotta

  • ASTM C457 air-void analysis to assess adequacy of air structure in concrete

  • ASTM C666 for concrete and modified by ASTM C1364 for cast stone

  • Proprietary modifications for building stone including dynamic modulus (ASTM C215) and flexural strength determination (ASTM C880) as metrics for progressive decay

  • Frost dilatometry to determine critical degree of saturation

  • Salt crystallization testing as a proxy for magnitude of freezing damage

  • Petrographic examination to evaluate susceptibility of concrete and stone
