Sachpazis] Corrélations entre la dureté au marteau schmidt et la résistance à la compression simple et à la déformation (module young) de roches carbonatées Schmidt hammer has increasingly been used world-wide as an index test for a quick rock strength and deformability characterization. The reason is mainly due to its rapidity and easyness in execution, non destructiveness, simplicity, portability and low cost. Twentynine different types of Carbonate rocks from Greek territory and four ones from England have been collected and tested. The tests include the determination of Schmidt hammer rebound hardness, (N) number, Tangent Young's modulus, (Et), and Uniaxial compressive strength (U.C.S.). Finally, these parameters were correlated and regression equations, of high practical value, were estanlished among N, Et and U.C.S., all presenting high coefficients of determination (R2).
