The cement paste in concrete and mortar has been shown to have a pore size distribution different than that of plain paste hydrated without aggregate. For mortar and concrete, additional porosity occurs in pore sizes larger than the plain paste's threshold diameter as measured by mercury intrusion.

## Ahatract-Results of experiments using the Iosipescu test specimen in which axial compression has been introduced in addition to the shearing loads are reported here. Different crack paths and fracture modes were obtained depending on the presence or absence of axial compression. Computer model
A new analytical development of the seismic hydrodynamic pressu concrete dams is presented. The finite control volume approach hydrodynamic pressure using the continuity principle and the linea The derived pressure expression is a function of the relative crack and velocity terms are then recast in
An incremental-iterative procedure for the nonlinear finite element analysis of reinforced concrete structures is presented here. Solid concrete is modeled as a hypoelastic material, whilst cracked concrete (including fracture and aggregate interlock) is modeled with crack bands, according to the sm
