Specimens of paste, mortar, and concrete were tested to failure when subjected to different amount of lateral confining pressure. Two distinct modes of behavior were observed. A stress-strain relationship includes two basic material constants: bulk modulus and Poisson's ratio. These material properties are considered functions of invariants of stresses; the appropriate functions are derived from test results.
