Implementation of ASTM C157: Testing of Length Change of Hardened Concrete

The Kansas Department of Transportation (KDOT) has a history of using tests such as concrete strength, permeability, and air void structure as design and acceptance criteria on concrete paving and bridge deck projects. In 2012, the KDOT Concrete Research group concluded a study on testing the length change of hardened concrete according to ASTM C157 (2008), commonly referred to as free shrinkage. This free shrinkage test was reviewed as a possible design or acceptance test for construction projects, primarily relating to bridge decks where even minimal cracking is detrimental. ASTM C157 has been successfully implemented at KDOT’s central testing laboratory should future testing be required. However, the equipment required and the conditions under which this test is conducted would indicate that this test would have to be conducted by private laboratories and not by Kansas contractors. This may preclude this test from being incorporated as a design or acceptance requirement.
