Data repository for 'Effect of ambient humidity on the elasticity and deformation of unweathered granite'

D1 and D2 provide data of porosity and pore size distribution measurement by mercury and adsorption porosimetry, respectively. D3 and D4 present raw data exported from the testing machine during uniaxial compression test on granite and aluminum specimens, respectively, exposed to humidity variation.

Digital images of the Herrnholz granite subjected to constant uniaxial compressive stress of 0.1 MPa, and varying relative humidity from 20% to 90% are proved in D5. We used an open-source 2D digital image correlation (DIC) software Ncorr to track surface displacement and strain of specimen during humidity variation. Resulting data (displacement and strain), along with image information, and DIC settings are shown in D6.
