Industrial applications: Aggregates and rock powders as filler.
Natural stones as raw materials often possess hidden qualities and properties, chemical or mineral components that make them unique in their availability and use. Rock deposits were formed differently depending on the millions of years of the earth's history and thus endowed with a wide variety of properties. Thereby, so-called industrial minerals, natural aggregates can be directly processed for industrial purposes without being subjected to any further treatment or transformation process.
