Conductive
concrete is a relatively new material technology developed to
achieve high electrical conductivity and high mechanical
strength. Conductive concrete has been used for anti-static
flooring, electromagnetic shielding, and cathodic protection of
steel reinforcement in concrete structures.
The main objectives of this research are:
(1) Design a conductive concrete mix
specifically for bridge deck overlay for deicing and anti-icing
application;
(2) Evaluate properties of the new
conductive concrete mix to ensure that the mechanical and
physical properties meet the ASTM and AASHTO specification for
overlay;
(3) Conduct deicing and anti-icing
experiments using conductive concrete overlay in a natural
environment to determine factors affecting the deicing and
anti-icing performance; and
(4) Provide a feasibility study for
using the new material as a heating system for bridge deck
deicing applications.
