Determining the Freeze-Thaw Resistance of Concrete Incorporated in an Existing Structure

Abstract

The paper discusses means of testing the freeze-thaw resistance of concrete, which is part of an existing structure. Practically all standards and regulations dealing with freeze-thaw resistance describe tests that require cast prism-shaped specimens. This can make determining the freeze-thaw resistance of a concrete part of a structure rather difficult. The paper discusses the problem in detail, proposes solutions, and presents a real-world example of determining the freeze-thaw resistance of bridge abutments.
