Overview
ELECTROCONCRETE is a conductive cement-based composite enabling active thermal management (de-icing), structural health monitoring (embedded sensing), electromagnetic shielding. By embedding conductive elements into concrete, it carries electric current while maintaining structural integrity. Primary applications: runway de-icing, bridge heating, smart pavements, structural monitoring.
Applications
Runway/taxiway de-icing, highway/bridge deck heating, parking structure heating, sidewalk thermal management, structural health monitoring. Typical scenarios: eliminate salt/sand application, reduce maintenance costs, real-time structural monitoring. Users: airport authorities, transportation departments, municipalities, critical infrastructure operators.
Operating Principle
Voltage applied generates joule heat (100–500 W/m²), raising surface temperature above freezing. A proprietary conductive filler blend, engineered around Arbok's own advanced carbon materials, is dispersed through the cement matrix at a loading level tuned to form a continuous, percolated conductive network without compromising structural strength. Heating prevents ice accumulation; sensing via resistance monitoring detects strain and environmental changes.
