Title: Influence of C3 A Content of Cement on Frost and Scaling Resistance of Concrete
Author(s): J. Stark and H. M. Ludwig
Publication: Special Publication
Appears on pages(s): 207-218
Keywords: air void; deicers; ettringite; frost; scaling
Abstract:The effects of chemical transformation processes on the frost and frost-deicing salt resistance of concrete are much less significant than the physical effects, but they are nevertheless significant. Our investigations showed that monosulfate (AFm phase) is particularly instable and will transform to ettringite (AFt phase) under frost and also under frost-deicing salt attack. This delayed formation of ettringite, which is supported by thermodynamic conditions at low temperatures, may reduce considerably the frost and frost deicing salt resistance of concretes without air-entrainment.
