Research into advanced cement technologies has focused on integrating functional biological and electrical properties into building materials.

Initial developments at Aalborg University explored ‘living cement,’ a material designed as a habitat for microorganisms. This approach aims to enable self-repairing capabilities through calcium deposits and the use of electroactive bacteria to allow buildings to store and release energy.

Subsequent advancements have produced 3D-printable, cement-based supercapacitors. By incorporating carbon black and carbon nanotubes, researchers created a conductive ink capable of forming electrode patterns within concrete. These supercapacitors are designed to provide rapid bursts of power for sensors and lights, integrating renewable energy storage directly into urban infrastructure while maintaining structural integrity comparable to commercial concrete.
