ELECTROCONCRETE

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.

Architecture and Components

Cement matrix; proprietary advanced-carbon conductive filler blend; embedded metallic electrode mesh; protective coating; power supply (12–240 V); monitoring/control system (temperature sensors, current sensors, controller). Installation: precast panels, in-situ casting, retrofit overlay.

Advantages

Technical: integrated heating/sensing, complex shapes, structural preservation. Economic: eliminates $5–10k/year de-icing cost per runway mile, 20+ year lifespan. Environmental: eliminates chemical de-icers (salt), reduces ecosystem damage. Operational: automated control, real-time monitoring, faster response.

Integrations

Deployment & Operation

Path: site assessment → design → lab testing → pilot (100–500 m²) → monitoring → scale-up

Operation: −40 to +40 °C, automated control, minimal staffing, electrical inspection annual, surface cleaning seasonal, coating reapplication 5–10 years

TRL

TRL 4 (Lab validation)

Evidence: formulations tested, heating/sensing demonstrated on small coupons, freeze-thaw testing in progress, no field deployment

Remaining: pilot on non-critical infrastructure, real climate validation (2+ winters), long-term durability, standards certification

Market Potential

Target: airports, highways, cold-climate regions, critical infrastructure

Drivers: climate variability, environmental salt restrictions, labor shortages, smart infrastructure demand

Market size: 5,000+ commercial airports (50–100 M m² runway), millions km highways → $2–5B annually

Risk Factors

Technical: freeze-thaw durability validation, electrical safety in wet conditions, conductivity fade, electrode corrosion. Market: regulatory standards uncertain, conservative infrastructure operators, cost premium vs. conventional methods. Operational: power supply reliability, maintenance complexity, public safety liability.
