Abstract: RILEM Technical Committee 176-IDC was formed in 1997 with the purpose of examining the internal deterioration of concrete due to frost action.
This committee was a natural successor to RILEM Technical Committee 117-FTC, which primarily focussed on surface scaling of concrete due to frost action.
The scope of the committee included both theoretical considerations and physical testing.
Topics at the micro level included mechanisms for the development of stresses (due to freezing and thawing), moisture transport, crack propagation (including fracture mechanics), and chemical effects (secondary ettringite formation at low temperatures).
At the macro level, the committee considered the role of non-frost resistant aggregate particles (including stress distributions around particles), the aggregate-matrix interface, temperature and concentration gradients, and the effects of carbonated layers.
The committee also considered the effects of different types of cements, admixtures, additives, and recycled materials.
The physical testing portion of the committee’s scope included considerations of specimen preparation and storage, thermal and moisture conditions during the freezing and thawing, and quantification of moisture uptake and damage produced in the specimens.
The damage quantification included a variety of non-destructive procedures as well as destructive (strength) testing.
Testing reliability and factors affecting repeatability were also considered.
The committee also considered using their findings to predict long-term concrete performance (service life).
