Freeze-Thaw Cycling Effect on the Constrained Modulus and UCS of Cementitiously Stabilized Materials
This study evaluates the effect of freeze-thaw (F-T) cycling on the mechanical properties of cementitiously stabilized materials (CSM). Ultrasonic testing was applied to monitor the P-wave velocity (constrained modulus) change during the F-T cycling. Unconfined compression strength (UCS) test was performed at the end of F-T cycling. It was found that F-T cycling could be detrimental to CSM as the constrained modulus decreased to 7% to 96% depending on the CSMs. The residual UCS was 35% to 84% of the initial UCS at the end of the test. It was found that the greater the cement content, the stronger the anticipated durability. Clay-lime and silt-fly ash showed limited resistance to F-T cycling.
