Summary
The effect of aggressive environments on concrete can conveniently be studied by observing the resultant changes in the dynamic modulus of elasticity of test specimens. An apparatus for rapid and accurate measurement of the fundamental transverse and longitudinal frequencies of a 1 × 1 × 11 in. concrete specimen is described. Typical experimental results are presented.
