Effects on static and dynamic characteristics of concrete due to freeze-thaw cycles

To investigate the influence of freeze-thaw cycles on static and dynamic mechanical properties of concrete,a series of uniaxial static compression tests and split Hopkinson pressure bar(SHPB)impact test of a C60 concrete after different times of freeze-thaw cycles were carried out with the "quick freezing method" in plain water and salt water respectively,and the reasons for the changes of concrete strength were analyzed.Tests show that the loss of mass and the loss ratio of relative dynamic elastic modulus of concrete specimens increase with the times of freeze-thaw cycles both in plain water and in salt water,which is more obvious in salt water.In the plain water environment,the freeze-thaw cycles decrease the static compressive strength of concrete significantly,while it has less influence on the dynamic compressive strength of concrete.In the salt water environment,significant strain rate dependency is observed on the dynamic strength of concrete after freeze-thaw cycles,while the dynamic compressive strength itself is affected little by the freeze-thaw cycles of fewer times.Nonetheless,the dynamic compressive strength decreases obviously with the times of freeze-thaw cycles when the cycle times is greater than 240 and it seems no longer sensitive to the impact velocity,indicating agreat difference in the effects of different freeze-thaw conditions on the static and dynamic strength of concrete.
