Concrete Permeability Apparatus

Concrete Permeability Apparatus – 6 Cell with Compressor

The Concrete Permeability Apparatus tests the water permeability of hardened concrete under constant pressure, measuring the depth of water penetration as a key indicator of concrete durability and impermeability. The 6-cell configuration allows simultaneous testing of multiple specimens — ideal for QC labs with high throughput.

Test Principle

Concrete specimens (cylinders or cubes, typically 150 mm dia × 150 mm or 150 mm cubes) are subjected to a constant water pressure of 500 kPa (5 kgf/cm²) for 72 hours. After testing, the specimens are split and the maximum depth of water penetration measured. IS 456:2000 specifies penetration limits for different exposure conditions.

IS 456:2000 Permissible Penetration Depths

• ≤ 50 mm: Acceptable for mild and moderate exposure
• ≤ 25 mm: Required for severe exposure (chloride, marine)

6-Cell Apparatus Specifications
