The most important feature of a reinforced concrete
structure is its ability to maintain performance until the end of its service
life. Here, the performance of both concrete and reinforcing steel is
important. When the reinforced concrete structure is examined, it is seen that
it consists of reinforcing steel and surrounding concrete. If this concrete
cover can sufficiently surround and protect the steel, it can work together for
many years. Concrete casting and maintenance in accordance with the rules, keeping
the concrete permeability at the lowest level, leaving enough Concrete cover,
making the appropriate curing, water / cement ratio are the main features
sought for concrete quality. The quality of concrete, working with reinforcing
steel and non-corroding of the reinforcement are very important for its
performance life. In addition, the concrete produced must fulfill its duty
against corrosion. As a result of material and workmanship defects, the
concrete, which is in a high permeable state, becomes exposed to external
influences, breathing more oxygen, water and chloride into it and its alkali
structure may deteriorate more rapidly. In the researches, it was observed that
the biggest problem occurred as a result of the damage caused by the corroded
reinforcement to the concrete. If the concrete surface deforms, it becomes more
open to external factors. As a result of the negative effects of external
factors, the building element fills the service life with great speed.
Structures whose service life has expired or decreased have been exposed to all
kinds of danger and carry a great risk in life. Thanks to the measures that can
be taken to reduce these effects in reinforced concrete structural elements,
the life of the building can be kept at the desired levels.
