2020-10-15 · The highest uniaxial compressive strength and modulus of elasticity values were measured in the case of andesite-9 (Figs. 6 and 7). Contrary to what was suspected, andesite-9 provided lower indirect tensile strength than other lithotypes, and andesite-1, andesite-2, andesite-3 and andesite-6 produced higher values in dry conditions.
