Relation between Parameters of Plasters Measured by Non-Destructive and Destructive Methods

Main target of this study is a comparison of material properties of plasters, which were obtained with use non-destructive methods and destructive methods and find out relation between them. These parameters were investigated on plasters. In this research the destructive methods were focused in obtain three parameters: the compressive strength, the tensile strength and the modulus of elasticity. For non-destructive testing was used pulse velocity method. Testing was carried out on specifically fabricated test specimens. With this study were obtained relations of the parameters for each type plasters measured with the non-destructive methods and with the destructive techniques. Obtained data were compared and then evaluated. These relations are very important and necessary for possibility to eliminate destructive methods in future.
