Corrosion of reinforcement in HVFA concrete – I

Hcfa concrete is an ideal environment for steel but the increased use of deicing salts and the increased concentration of carbon dioxide in modern environments principally due to industrial pollution, has resulted in corrosion of the rebar becoming the primary cause of failure of this material.

Because corrosion is a diffusion controlled process, it occurs on corrosion of reinforcement in hvfa concrete surfaces. This deterioration is most
