Abstract


CHANGEABILITY OF RESISTANCE OF SANDSTONES UNDER CONDITIONS OF CRYSTALLIZATION OF SODIUM SULFATE AND UNDER INFLUENCE OF SULFUR DIOXIDE

Abstract. The purpose of this study was to determine changes in geomechanical properties of two kinds of sandstones (Szydłowiec and Godula) during modeling of salt crystallization process as well as SO2 action in the presence of humidity. The estimation of resistance was based on uniaxial compressive strength tests. The unweathered samples were taken from two quarries in Poland – Śmiłów and Głębiec (in Brenna). The results indicate that the analyzed sandstones are more susceptible to reduction of uniaxial compressive strength during the crystallization of sodium sulphate rather than as a result of SO2 action in the presence of humidity.
