Introduction

Sandstones are encountered in many underground excavations and mines, and in addition, because of their abundance, they are commonly used as building stone and aggregate material for dams, railway or airport foundations, and other infrastructures (Shakoor and Barefield 2009). Therefore, understanding the mechanical behavior of sandstones and how they are affected by environmental factors such as saturation or temperature is clearly important. A number of experimental studies have shown that various sandstones could suffer a significant loss of uniaxial and confined compressive strength upon saturation (Colback and Wild 1965; Burshtein 1969; Hawkins and McConnell 1992; Vasarhelyi 2003; Lin et al. 2005; Li et al. 2005; Aydan 2012; Duda and Renner 2013; Wasantha and Ranjith 2014). For clay-bearing rocks, the saturation-induced reductions in strength and stiffness can be up to 80 % (Cherblanc et al. 2016; Vergara and Triantafyllidis 2016). In contrast, Reviron et al. (2009)...
