The reinforced concrete assets such as bridges, tunnels, administration buildings, schools and the
buildings are important factors in the Egyptian economy. Several researches have been made in the field of
defects and methods of repair. Concrete can
for a variety of reasons such as the
of steel bars, design errors, construction errors and the
conditions. Concrete structures’ deterioration is often the result of a combination of deterioration factors. Factors that contribute to the
of the
concrete structures can be classified into five categories as follows: (1) Design factors such as the code requirements, the structural system, and the foundation design; (2) construction factors such as the mix design and the
control; (3) protection factors such as the thermal
and the water proofing; (4) material factors such as the
and the cement; and (5) the applied loads factors such as the chemicals and the
. This paper provides a model for prioritizing the concrete structures’ repair works.
