MCI® Repair Grout Stops Rust On Reinforcing Bar

MCI® 2023 Passivating Grout forms a cement slurry that cures to a water-repellent barrier on steel reinforcing bars used in concrete structures. The MCI® Grout seals out moisture, water, and water-solubilized salts. It stops the attack of deicing salts, saltwater, and carbonation which readily cause concrete deterioration. During the repair process, the grout applies easily to provide years of long-term protection.

Effective for all types of steel rebar, the MCI® 2023 Passivating Grout works very effectively for reinforcing steel that is close to the surface and has only a thin layer of concrete. This surface type of rebar is the most susceptible to fast, aggressive attack from corrosive elements of solubilized salts and carbonation. Corrosive agents quickly penetrate through the thin top layer of concrete and immediately start to rust any open area of steel rebar. The rust easily causes the concrete to crack, enabling even faster transfer of corrosive agents, and then finally concrete spalling, flaking, and exposure of the rebar itself to the elements.

The strength and durability of MCI® 2023 Passivating Grout come from a two component system that is mixed together on-site. One part is a powder formulation consisting of hydraulic binders with complexing and osmotic agents that provide a high degree of passivation to the metal. The second component is a water-based emulsion of organic polymers. When mixed, they form a slurry with excellent adhesion to rebar and other surrounding substrates. The slurry is easily applied with a brush, multiple coats can be applied as necessary. After the rebar has been coated with the repair grout, mortar can then be applied with conventional techniques.

The cured grout forms a resilient barrier against water and corrosive agents. Further, it incorporates Cortec® MCI® technology. This patented chemistry provides self-replenishing corrosion inhibitors that protect the rebar metal surface at the molecular level to block the oxidation and rust process from starting. The MCI® material will migrate through the concrete to other adjacent reinforcing bars to aid in their protection.
