Uniaxial, biaxial, and triaxial tests were performed on three-inch cubes using various combinations of compressive and tensile loads. One nominal concrete strength of 4000 psi was used in the testing. The testing machine and its associated hardware such as load cells, platens, and extensometers were designed as a part of this study. The test information was obtained as stress- strain records for the three principal directions of the cubical test specimens. The tests were run until the largest compressive stress reached 30,000 psi or there was a tensile failure. Whenever possible the test results were compared to those of other investigators. A model to simulate concrete behavior was developed.
