CARBONATION DEPTH IN HARDENED CONCRETE

CARBONATION DEPTH IN HARDENED CONCRETE


The test is used to determine carbonation depth in concrete structures that have suffered or may suffer damage or deterioration due to calcite and other alkali-carbonate products resulting from exposure to prolonged moisture and chemical attack. Carbonation in concrete surface results in corrosion of embedded steel reinforcement and can damage structural stability and life span of the concrete structure.

This test is used to detect carbonation activity at earlier stages in old concrete structures especially bridges and concrete structures exposed to chemically corrosive environments.
