Carbonation Depth Test.

Assessing the Loss of Alkalinity and Corrosion Risk in Concrete

Carbonation Depth Test is a vital durability and diagnostic test that determines the extent of carbonation — the chemical process that reduces the alkalinity of concrete, thereby making embedded steel reinforcement susceptible to corrosion. At Global Lab, we perform the Carbonation Depth Test with precision indicators and calibrated core samples to measure the penetration of carbon dioxide (CO₂) into concrete. This allows engineers to assess corrosion risk, evaluate service life, and design effective rehabilitation strategies for aging or exposed structures.

Why Carbonation Depth TestMatters.

Evaluates Corrosion Risk of Reinforcement

By identifying how deep carbonation has penetrated, engineers can determine whether the carbonation front has reached the steel reinforcement level — a key indicator of corrosion likelihood.

Assesses Concrete Quality and Permeability

Dense, low-permeability concrete resists CO₂ ingress, while porous concrete carbonates faster. The test helps evaluate construction quality, curing efficiency, and material performance.

Supports Service Life & Maintenance Planning

Carbonation rate data allows engineers to model future deterioration, estimate remaining service life, and plan preventive repairs or coatings accordingly.

Validates Protection and Repair Effectiveness

Used after surface coatings or rehabilitation work to confirm whether protective treatments are effectively slowing carbonation progression.
