Influence Of Reinforcement Distribution In The Corrosive Process Of Reinforced Concrete Beams

摘要

The current paper presents results from an experimental study monitoring the behaviour of reinforced concrete beams with different reinforcement dispositions (stirrups and main longitudinal reinforcement) that have undergone a galvanostatic process of accelerated corrosion. The changes in the cracking of the concrete cover in beams with different spacing of stirrups are comparatively analysed. In the same way, several dispositions of the main reinforcement are analysed (keeping the section constant). Some assembly criteria are to be considered by designers of concrete structures, as an additional parameter that should be taken into account besides those traditionally considered, to minimise the cracking that originates in the corrosion of the beams by limiting the presence of aggressive agents that may enhance the corrosive process.
