For twenty-five years The ASTM method used to determine reductions in concrete durability after freeze-thaw cycling has been C215-60. In this test the fundamental frequencies of a concrete specimen are compared. This test is time consuming, noisy and often inaccurate. In this paper a new method is proposed for measuring the fundamental frequencies of concrete to a single tap via a Fast Fourier Transform. The new test is faster, simpler and more accurate.
