Lithium Nitrite Internal Pressurization Method "ASR Lithium Method"
A repair method that can fundamentally suppress alkali-silica reaction (ASR)!
By pressurizing and injecting lithium nitrite into the entire concrete member, it is possible to non-expand the alkali-silica gel, which is the cause of ASR, fundamentally suppressing further deterioration. This method is also effective for structures that cannot tolerate re-deterioration due to moisture supply. 【Construction Procedure】 1. Seal the surface of the member with polymer cement mortar. 2. Drill holes of φ20mm at intervals of 750mm in the concrete structure. 3. Inject lithium nitrite into the entire member using a pressurization device (injection duration: approximately 20 to 30 days). 4. Fill all injection holes with non-shrink grout material. *For more details, please refer to the PDF document or feel free to contact us.
