NT BUILD 492 Concrete Chloride Ion Diffusion Coefficient Tester
The NT BUILD 492 Concrete Chloride Ion Diffusion Coefficient Tester quantitatively evaluates concrete's resistance capacity to chloride ion diffusion. Based on DuraCrete unsteady electromigration test theory, this equipment provides essential parameters for designing and assessing the durability of concrete structures in chloride ion erosion environments.
This tester is suitable for concrete specimens with maximum aggregate size not exceeding 25mm (typically not more than 20mm), whether laboratory-produced or core samples. The resulting data serves as a foundation for concrete durability mix design in chloride environments and for quality inspection and assessment.
