Total Corrosion Protection

EXTEND-THE LIFE OF CONCRETE STRUCTURES

 

Concrete structures reinforced with steel bars (rebar) lose strength over time from exposure to elements causing corrosion (chlorides,air {02 and C02) and water)

 

Rebar corrosion causes structure deterioration and expensive repair cycles leading to eventual loss of use.

 

Corrosion caused loss of steel from the rebar reduces strength and the rust expands causing concrete to crack and spall.

 

Rebar corrosion is an electrochemical process. Corrosion rate can be measured by the electric current produced.

 

Rebar corrosion is promoted by changes in the concrete chemical condition (chlorides and carbonation) and can be inhibited by changes in cement properties and on rebar surface.

 

Corrosion current is correlated over time with loss of rebar steel or diameter measures as micrometers of steel lost per year.

 

A chemical formulation of QuantiShield  (Surtreat  TPS II) is applied  to the surface of concrete and migrates to the rebar surface and inhibited rebar corrosion by stabilizing rebar corrosion resistant surface, reducing cement porosity and the water soluble chloride content.  The powerful anodic site functioning corrosion inhibitor has reduced the corrosion hot spots by a greater degree than the average rate.
