Repair and reinforcement method ASR lithium method
The "alkali-silica reaction" that deteriorates concrete structures, which were said to be maintenance-free, and even reduces their strength. Initially, it was believed that the damage was limited to surface cracking of the concrete, but recent investigations have pointed out the possibility of internal concrete deterioration and rebar fracture, making the issue more serious. 【Features】 ○ By pressurizing and injecting an ASR suppressor primarily composed of lithium nitrite, it effectively penetrates and diffuses through the fine cracks in the internal concrete of the structure, reducing future expansion of the internal concrete and suppressing further deterioration due to ASR. ● For other functions and details, please download the catalog.
