Database of high-temperature rock properties

This comprehensive database, consisting of 22 individual Excel files, rigorously compiles over 10,000 temperature-property pairs and 1,360 temperature-property evolution curves for a diverse range of rock types, including igneous, sedimentary, and metamorphic samples.

The properties included in the database are: mass loose, volume change, density, specific gravity, porosity, absorption, P- and S-wave velocity, uniaxial compressive strength, elastic modulus, Poisson's coefficient, Brazilian tensile strength, point load index, flexural strength, friction angle, cohesion, mode I and mode II fracture behaviour, thermal conductivity, specific heat capacity, thermal expansion coefficient, and permeability.
