Porous inclusions such as LWAs embedded in a cementitious matrix are filled with multiple fluid phases including PCM to obtain desirable thermal properties for building and infrastructure applications.
Indeed, fluid inclusions (tiny bubbles of fluid trapped within mineral grains) in eclogite samples provide evidence of fluids containing nitrogen, salts, and carbon dioxide in addition to water.

Analyses of fluid inclusions hosted by rocks of the Shimanto belt in Kyushu reveal that the fluid salinity is similar to or lower than that of seawater27.

There may be multiple fluid domains and multiple solid domains.
These circular structures are discounted as fluid inclusions based on their larger size (20 × larger than typical fluid inclusions at 10 μm diameter) and their occurrence in a polymineralic matrix7.
