This can certainly be interpreted in a variety of ways, but for the concrete industry, it’s about building for the longest possible lifespan. Unfortunately, there is evidence piling up all over the world that sustainable building isn’t taking place.
The deterioration of concrete structures, as it is the most used man-made material in the world, causes a strain on our environment. Costly repairs, teardowns, and rebuilds mean we have to continually pull resources for projects that should have been done correctly in the first place.
One manner is which concrete structures deteriorate and weaken is through corroded steel rebar. Rebar is extremely important for concrete structures because though concrete has extremely high compressive strength, its tensile strength is low. The addition of steel rebar in the concrete strengthens this; ensuring concretes structural viability in all aspects.
However, corrosion of steel rebar in reinforced concrete is a significant problem, evidenced with deteriorated structures throughout the world. Therefore, blocking the flow of moisture by properly waterproofing the concrete is essential.
