Lithium Nitrite Containing Body Repair Method - Revamp Method for Long Lifespan Renovation

By utilizing the power of nitrite and lithium ions, a rust prevention environment is established for reinforced concrete structures that have deteriorated due to neutralization and salt damage, contributing to the longevity of the structures.

The "Revamp Method" is a construction technique that uses RV aqueous solutions or RV mortar containing a high concentration of lithium nitrite (LiNO2). Due to its high suppression effect, it prevents the intrusion of external deterioration factors. By allowing nitrite ions to permeate around the internal rebar, it generates a rust prevention effect for the entire internal rebar of concrete structures that have deteriorated due to salt damage and carbonation, thereby regenerating the passive film. This method is suitable for repairing the structural bodies of all reinforced concrete structures, including bridges, tunnels, roads, embankments, and subways. 【Features】 ■ Generates a rust prevention effect for the entire internal rebar and regenerates the passive film. ■ Creates a rust prevention environment for internal rebar through the diffusion of nitrite ions. ■ Prevents the intrusion of external deterioration factors (carbon dioxide and chloride ions) due to the high suppression effect of the rust prevention mortar. *For more details, please refer to the PDF materials or feel free to contact us.
