Abstract: The thermophysical properties of natural and artificial samples of marble were investigated to determine how the marble would respond to solar irradiation. The thermal conductivity, specific heat and density were all determined experimentally for the marble samples, and the thermal diffusivity was calculated using these properties. It was determined based on the thermal diffusivity values that heat travelled faster through the natural samples than it did through the artificial samples. The solar reflectance index (SRI) was calculated to be higher than 100, which indicates that marble is highly effective at reflecting sunlight, and therefore it is a good material for roof coverings.
