DEVELOPMENT AND TESTING OF MINERAL CASTING FOR USE IN STRUCTURAL ELEMENTS AND MOLD MAKING

The paper presents the making and the testing of different formulations of mineral casting, with the aim of identifying formulations with excellent mechanical properties for use in machine-tool structural elements and mold making. It describes the manufacturing process of this composite material from epoxy resin and granite. Specimens of different material formulations were cast and experimentally investigated by flexural testing. Individual stress-deformation graphs were plotted for each specimen and the average results for the many different formulations were compared.
