In this study, the strength properties of traditional plaster materials were experimentally investigated. Material tests in compression, bending, and shear were conducted to clarify the basic performance. It was shown that the stiffness and strength of the plaster decreased as the amount of sand mixed into the plaster increased. The stiffness and strength of the plaster increased with increasing curing time. Furthermore, a comparison of the average values of compressive, bending and shear strength showed that there was a correlation among those values. These results quantitatively clarified the various properties of plaster materials, although they are limited to certain formulations.
