Material properties of Godula sandstones and forms and reasons of their deterioration in constructions in industrial environment of the Ostrava region
Original language description
The Upper Cretaceous green glauconitic sandstones, referred to as Godula or Tˇešín sandstones according to their stratigraphic position or area of mining, represent a traditional building and decorative stone widely used since the turn of the 19th and 20th centuries in constructions in the industrial region of Ostrava and adjacent part of the Tˇešín Silesia. In terms of their physical and mechanical properties, the sandstones can be characterized by high values of bulk density, low absorption capacity and low total porosity, high abrasion resistance, high to very high values of strength properties and high fracture toughness. Due to their high compactness and strength, they can get relatively good polish, as one of few sandstones mined in the Czech Republic. However, in contrast to high quality of physical and mechanical properties of the Godula sandstones, degree of their durability in the case of exterior use is often very low.
