Green Concrete is a term given to a concrete that has had extra steps taken in the mix design and placement to insure a sustainable structure and a long life cycle with a low maintenance surface.
First step in creating a Green Concrete is to waterproof it ASAP. This Stabilizes the concrete to inhibit the internal chemistry from reacting with an atmosphere to cause surface degradation problems. A product called StableCrete can be used to penetrate into a concrete where it forms a solid inside the gel-pore/capillary system that gives waterproofing protection for a warranted 15 year period! [yes concrete is porous and absorbs water].
A waterproof concrete does not allow contaminates [chlorides being the worst] to enter the matrix and form corrosion cells on the re-inforcing steel [re-bar]. Rust on steel occurs when the pH of the concrete drops below 11.5 thus destroying the passivating protective layer on the steel. A Stabilized concrete treated with StableCrete, reduces the moisture and oxygen content, two of the four ingredients needed for corrosion to commence.
Concrete will last longer and will not need a repair or replacement if protected from the start. This makes it “Green”
