Title: CRC 74: Mitigation of Steel Reinforcement Via Bioactive Agents
Author(s): Aaron R. Sakulich and Jessica D. Schiffman
Appears on pages(s):
Abstract:The corrosion of reinforcing steel in concrete can reduce the service life of a structure [1, 2]. This phenomenon is commonly initiated when a structure is exposed to aggressive media (e.g. deicing salts or seawater) which depassivates the steel and leads to the formation of rust . Since rust expands during creation, pressure is generated that leads to cracking and spalling [4, 5]. Cracks are particularly undesirable because they allow easier access for aggressive media to travel through the cementitious matrix, accelerating deterioration [6, 7]. Although many corrosion mitigation methods are on the market today, $100 billion is still being expended worldwide each year on corrosion related damage . New corrosion mitigation methods are needed.
