Mechanical Properties and Schistosity of Green Crystalline Schist

Abstract

This is a brief report on a testing strength of green crystalline schists sent from Sazare copper mine, Shikoku district.
Green crystalline schist is well laminated with the schistosity. Then the mechanical properties are characterized by the schistosity. Tensile strength by Brazilian method, compressive strength, and Young's modulus were measured on specimens of green crystalline schist prepared from boring cores which were cored in parallel and perpendicular to the schistosity.
Significant different values were recorded on the tensile strength concerning with the direction of specimen to the schistosity. And also, it was found from microscopic observations of specimens that these differences were due to their crystalline or structural natures.
