Thermal Mass:
A building material, typically one that is fairly dense such as stone, ceramic tile, concrete, plaster or brick that is  used to store heat and reduce temperature fluctuation in a space. This is accomplished when the material absorbs heat while the air is warmer than it and then releases heat slowly over time once the air temperature has dropped. Thermal Mass is typically employed in conjunction with passive solar heat.
