• Measures both air and water permeability at the same time.
• Permeability measurements at the surface as well as within the concrete mass can be determined.
• The porosity of sealants and surface mortars can be checked.
Permeability, an important parameter in assessing concrete durability, can be accurately measured by this unique field test system.
In air permeability test applications, the system measures the time it takes for air to flow into a known volume of a sealed, evacuated chamber in the concrete, while reducing the vacuum.
For water permeability testing, the device uses the same chamber, filled with water and measures the total time in seconds for a volume of 0.01 ml of water to escape.
Through the use of the Surface Chamber Kit, the system can be used to measure the surface porosity of the concrete.
