Energetic Consideration on Strength Decrease of Concrete Immersed in Liquid

In order to clarify the lowering effect of an immersion liquid on the compressive strength of concrete, nucleation of internal cracks under static compression was investigated on the basis of surface energy. The energy consumed in the nucleation of cracks is calculated from the area of hysteresis loop on the stress-strain relationship in the compression test. As a result, it turned out that the calculated energy is closely related to the surface energy in the nucleation of cracks. It is also found that the energy increases exponentially with the increase of strain, and decreases with increasing of surface tension of immersion liquid under the same strain ratio. It is concluded that the compressive strength decrease of concrete immersed in liquid results from the decrease of surface energy consumed in the nucleation of internal cracks.
