By injecting KK grout mixed with rust inhibitor, macrocell corrosion is suppressed!
We would like to introduce our "KK Grout Injection Method." In post-tensioned PC structures, when there is a cavity within the sheath through which PC steel materials are inserted, a powdered KK rust inhibitor is pressed into the cavity inside the sheath. Next, grout (KK grout if necessary) is injected into the cavity. This method suppresses the corrosion of PC steel materials through injection. 【Features】 ■ By pressing powdered KK rust inhibitor into the cavity, PC steel materials are protected from rust. ■ By injecting KK grout mixed with the rust inhibitor, macrocell corrosion is suppressed. *For more details, please refer to the PDF materials or feel free to contact us.
