Check out the first two videos on concrete if you haven't seen them already: - What is Concrete? (https://www.youtube.com/watch?v=UOHURuAf5iY) - Why Concrete Needs Reinforcement (https://www.youtube.com/watch?v=cZINeaDjisY) While steel reinforcement solves one of concrete’s greatest limitations, it creates an entirely new problem: Corrosion of embedded steel rebar is the most common form of concrete deterioration. There are lots of ways to combat this problem, a few of which we discuss/demonstrate in this video, including fiber reinforced concrete, adequate protective cover, and fiber reinforced polymer bars.
