Usually, the most exposed elements deteriorate first; however, much of the actual corroded reinforcement is not visible and it may take five to 15 years of active corrosion before cracks initiate in the concrete.

Resistivity Meter The resistivity of the concrete influences the flow of this current. The lower the electric resistance, the more easily corrosion current flows through the concrete and the greater is the probability of corrosion. Thus, the resistivity of concrete is a good indication of the probability of corrosion.

Will concrete corrode galvanized steel?

Corrosion can occur when concrete loses its high alkalinity (about a pH of 12.5 to 15). It can cause attack to and corrode steel, and regardless of pH can cause corrosion to some grades of stainless steel, galvanized steel (by definition, the galvanize coating is zinc), and aluminum.

Can concrete cause disintegration?

Concrete degradation may have various causes. Concrete can be damaged by fire, aggregate expansion, sea water effects, bacterial corrosion, calcium leaching, physical damage and chemical damage (from carbonatation, chlorides, sulfates and non-distilled water).

What causes rust stains on concrete?

Localised rust coloured stains on the concrete surface may be caused by small amounts of contaminants in the aggregate, such as pyrites. These can be avoided by careful selection of the aggregate and control of its production and storage prior to use.
