Porous ceramics, characterized by their microstructured porosity and material composition, are increasingly integrated into cement and concrete applications to leverage their unique thermal, mechanical, and durability properties. The intrinsic porosity of these ceramics is engineered through specific manufacturing processes that introduce air pockets or voids within the ceramic structure, which can significantly enhance insulation properties and reduce weight. In the context of cement and concrete, porous ceramics are used as lightweight aggregates to modify the physical properties of the concrete mix, enhancing its thermal resistance and decreasing its overall density. This integration also impacts the concrete’s mechanical properties, often reducing the compressive strength due to the inclusion of less dense materials, but improving its thermal insulation and fire resistance, making it suitable for severe environmental conditions where thermal management and fire safety are critical.
