New repair mortar

Dec 19, 2022 | News

Sustainability has become a buzzword in today’s construction market, with practical implications for building owners as well as the environment. Engineers are looking for ways to make buildings last longer to meet increasing service life demands and preserve an ageing infrastructure. However, in spite of the strength of concrete as a durable building material, repairs are an inevitable part of the concrete lifecycle. The good news is that the proper use of MCI Technology to mitigate concrete corrosion can help concrete structures and repairs last longer, ideally lengthening intervals between repairs and thus saving substantial time, labour, and money.

Cortec Corporation has launched its new, improved MCI-2040 High Performance Vertical/Overhead Repair Mortar. This is yet another component of Cortec’s High Performance Repair System (HPRS), which helps concrete repairs last longer by inhibiting corrosion and reducing the risk of the insidious ring-anode effect. With MCI-2040, Cortec has extended the protective qualities of MCI-2041 (horizontal repair mortar) to vertical and overhead surfaces, giving concrete contractors an MCI repair mortar for any angle!


Extending service life

MCI-2040 is a single-component, fast-setting, high-strength, cement-based repair mortar that is enhanced with Migrating Corrosion Inhibitors (MCIs). MCI-2040 offers corrosion protection to reinforcing metals both in the patch and in the surrounding areas. MCIs in the concrete repair mortar penetrate the substrate and even out corrosion potentials between patched areas and nearby concrete. This slows down the ring-anode/halo effect in surrounding concrete. Once applied and hardened, MCI-2040 provides a high level of adhesion and durability as well as resistance to water and carbonation attack. This increases the quality and extends the service life of the repair and surrounding structure.

MCI-2040 is an easy-to-handle patching material for fast-paced repair jobs. It offers quick turnaround due to high early strength and can be applied like normal repair mortars, but without the need for bonding agents. It is specifically designed for vertical and overhead repairs, greatly increasing the potential use and offering enhanced flexibility for contractors. Possible applications for MCI-2040 include the undersides of bridge decks, parking ramps, balconies, and ramps, along with concrete columns, retaining walls, building facades, and soffits.
