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. (more info www.StableCrete.com). 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"
It is the concrete which knows its condition itself.
Advantages of curing:Gains strengthYields microcracksReleases high heat of hydration.
Also known as Cyclopean Concrete, this is a variety of concrete consisting of large sized stones(Plums) with interstices filled with concrete. Used mostly in mass concrete works like concrete gravity dams
Concrete is durable, fire resistant, has long life, is energy efficient and important as an earthquake safety product
Using concrete flooring offers many advantages as well as disadvantages. Some of the advantages to using concrete flooring is the overall durability, the ease of maintenance, and the low negative environmental impact that concrete flooring has.

Concrete does not crack if done properly unlike wood.
Comprssive strength of concrete is more than that of brick.Waterabsorption is more in brick.Durability of concrete is more.
Advantages of curing:Gains strengthYields microcracksReleases high heat of hydration.
The main disadvantage of compacting concrete using a cement vibrator is the noise. The advantages of compacting concrete using a cement vibrator is to remove trapped air and excess water which then allows the concrete settle firmly.
Green concrete could mean two different things. It could mean that the concrete isn't cured yet, or it could mean that it is supposed to be environmentally friendly.

Concrete gives good strength to the structure, it is fire resistant and has life around 80 years.
Advantages of concrete:compression member.slabs.beams.shear walls.Disadvantages:Non-renewable source.Mix design should be known.Skilled labour is required to mix, handle, and place the concrete.
