From: Effects of groundwater and distilled water on the durability of evaporitic rocks

Representative evaporitic rock block (G1–RB; Group 1, Rock Block) and slake durability test samples cycled with distilled water and groundwater (1st–4th cycles). G1-FS-A represents Group 1, fresh sample, sample A, G1-A1C-DW to G1-A4C-DW after 1st–4th cycles with distilled water. G1-FS-B represents Group 1, fresh sample, sample B, G1-A1C-GW to G1-A4C-GW after 1st–4th cycles with groundwater. G = Gypsum, F = Fracture, CL = Clay.
