Mechanical Properties
Ductility and Yield/Tensile Strength
Ductility and strength of reinforcing steel
are important to prevent brittle failure of
reinforced concrete. Studies on the effect
of galvanizing on the mechanical properties
of steel reinforcing bars have demonstrated
that the tensile, yield, and ultimate strength,
ultimate elongation, and bend requirements
of steel reinforcement are substantially unaffected
by hot-dip galvanizing, provided proper attention
is given to steel selection, fabrication practices
and galvanizing procedures. The effect of
the galvanizing process on the ductility of
steel bar anchors and inserts after being
subjected to different fabrication procedures
has also been investigated. The results demonstrate
conclusively that, with correct choice of
steel and galvanizing procedures, there is
no reduction in the steel’s ductility.
Fatigue Strength
An extensive experimental program examining the fatigue resistance of
galvanized steel reinforcement shows that deformed reinforcing steel,
exposed to an aggressive environment prior to testing under cyclic
tension loading, performs better when galvanized.
