Product used: Ultrafine Cement U.P.-II 52.5

Application scenario: Hydraulic infrastructure reinforcement and seepage-resistant repair projects

Project Challenge: Large-volume concrete structures are experiencing micro-cracks and leakage, and traditional materials struggle to completely seal these issues.

Solution: The Kangjing series of ultra-fine cement, with its extremely fine particles and excellent micro-filling capability, achieves deep penetration and repair of cracks. It features a low shrinkage rate and outstanding bonding performance.

Engineering Results: Leaks have been completely sealed, the structural lifespan has been extended by 30%, and the project has successfully passed acceptance inspection.
