Properties, durability and use of glauconitic Godula sandstones: a relatively less known building stone of the Czech Republic and Poland

Original language description

Greenish glauconitic sandstones from the Middle Member of the Godula Formation of the Outer Western Carpathians flysch belt represent traditional building stone used in the north-eastern part of the Czech Republic and adjoining part of south Poland for about a thousand years. Despite the longstanding history of their utilisation in constructions and monuments, the amount of information about properties, durability and places of use is given in the existing literature only to a very limited extent. The Godula sandstones under study exhibit a high bulk density (up to 2610 kg/m3), relatively low water absorption capacity (0.7–3.0 wt%) and total porosity (1.7–9.4%), high values of P-wave velocity within psammitic rocks (3120–4290 m/s), and high to very high strength (uniaxial compressive strength 102.7–155.8 MPa, splitting tensile strength 4.0–10.0 MPa). However, in contrast to high quality of stone properties, the degree of their durability especially in the case of exterior use may often be very low, and stone deterioration can frequently advance very rapidly. Godula sandstones are characterised by a significant dominance of pores with diameter smaller than 1 μm. The character of pore space represents the principal and general reason of Godula sandstone deterioration susceptibility. Deterioration rate and specific weathering forms are subsequently strongly affected, in detail, by the heterogeneity of the mineralogical composition and anisotropy of rock texture within the individual sandstone bed. The data about composition, properties and stability of the Godula sandstones published in this paper could help architects or designers to understand the decay causes experienced by these types of sandstones and how to prevent them and may also serve as a guide for restoration and conservation works.
