How Does Cortec MCI Technology Work
The corrosive effects of carbonation and chlorides cause a breakdown of the natural passivating layer on steel in concrete. MCI’s provide protection because of their ability to migrate to the depth of the metal, and form a protective, molecular layer on steel when they come into contact with it. …

When the concrete is finished being cast in place, the condition of the concrete is in a very alkaline condition, it can reach 12.5, in this very alkaline condition the potential for corrosion becomes small, because there is a passive layer that protects the concrete from rust. […]

Chloride ions can penetrate the passive oxide film on the reinforcement. They combine with iron ions to form a soluble iron chloride that carries the iron into the concrete for later oxidation (rust). Once chlorides reach a level of about 0.15% (water soluble chloride by mass of cement) in the concrete, corrosion starts. […]

Cone of the latest technologies for structural concrete reinforcement is to use synthetic macro fiber, this material is very strong and has a high modulus. how to use it only by mixing this fiber into concrete with a certain dose, it can be used for readymix concrete or for precast industry. for cast in situ work, it is very suitable for use in casting slab on ground floors and composite floors for suspended slabs, and casting in coastal..
