Resumen
This database includes experimental results from mode I fracture toughness (KIC) tests conducted on saturated rock specimens. Three lithologies were studied: a porous siliceous sandstone (Corvio, C) and two high-strength, low-porosity granites (Blanco Mera, BM and Blanco Alba, BA). Tests were conducted at room pressure and temperature using the pseudo-compact tension (pCT) methodology. Seven different fluids were used: deionized water, methanol, NaCl-saturated water, mineral oil, diesel fuel, an acidic HCl solution, and a caustic NaOH solution.
