It is well known that the static and dynamic strength of cement based material are influenced by the water content, moreover its value is greatly dependent on the surface tension of the liquid. However, the mechanism for the effect of the surface tension of liquid on the solid strength has not been investigated yet. In the beginning, the cavitation phenomenon is incorporated to the developed model which is assumed to be a two phase porous material of solid and liquid and then the effect of the erosion of bubbles on the solid phase is estimated and compared with the experimental results.
