Making Concrete Structures More Sustainable with MCI(R)-2005
One of the biggest threats to concrete longevity is corrosion. Under static conditions, reinforced concrete is at very low risk for corrosion. However, when adding cracking, chloride exposure from seawater or deicing salts, and long-term carbonation to the equation, the vicious cycle begins. Corrosion causes reinforcing metal to expand, pushing on the concrete cover and causing it to spall off, subjecting the reinforcement to additional corrosives and deterioration.
For this reason, corrosion-inhibiting admixtures are often used in the construction of concrete buildings in harsh environments like seacoasts or regions that use heavy deicing salts. MCI®-2005 is one such admixture that meets the corrosion inhibitor requirements under ASTM C1582 and promotes greater concrete longevity.
MCI®-2005 stands out from the crowd as the only corrosion-inhibiting concrete admixture that is also a USDA-certified, biobased product. MCI®-2005 contains 67% USDA-certified biobased content and is therefore a great way to earn credits toward LEED certification through the use of renewable materials. It is also a good choice for US federal agencies and their contractors seeking to meet minimum biobased content purchasing requirements, or for projects seeking to meet Estidama Pearl and BREEAM green building rating requirements in other parts of the world.
