Corrosion - An Undesirable Phenomenon for Reinforcement of Advanced Mortars and Concrete
Constructions made out of mortar and cement concrete are unveiled to advanced chemical corrosion processes, especially when placed in aggressive environments. The study follows the behaviour of concrete with a slag content of 10 % exposed to chlorine corrosion, as well as carrying out analyses aimed at monitoring the evolution of mechanical resistance of concrete samples, containing slag when immersed in various aggressive solutions. The corrosive agents acting on the above-mentioned elements are in particular chlorine ions. These compounds may also be found in considerable quantities in industrial emissions and their effect is intensified by an increase in humidity, temperature or steam, or other corrosive gases, possibly accompanied by inadequate ventilation. The analysis of complex chemical processes highlights the influence of different corrosive agents on the resistance of this concrete.
