Compressive strength of concrete is usually corrected to predict so called true uniaxial compressive strength when the value is measured with specimens having height/diameter (h/d) of less than 2.0. As long as porous concrete is concerned, however, sufficient data is not obtained so far for the correction of the compressive strength. In the present study, a series of experiments was conducted to clarify the degree of influence of h/d ratio. As a result, it has been made clear that almost the same correction formula can be used for porous concrete as normal concrete. The proposed formula can be used also for core specimens from porous concrete structures to predict the relationships between the compressive strength and h/d of a specimen, as well as standard cylindrical specimens cast in molds.
