Sistemas de pasivación de corrosión en losas de hormigón armado.

Abstract

In the present degree work it is explained the problems that nowadays appear in concrete structures around America and all over the world due to the phenomenon known as "corrosion". It will be explained in detail the different types of corrosion that can occur and the consequences that each one entails. Likewise, treatment options will be given for structures that have been affected by this phenomenon and preventive methods to avoid or delay the beginning of the corrosion process. For the demonstration of the different existing methods, whether preventive or corrective, reinforced concrete slabs made more than 10 years ago have been used and these slabs have been replicated so that some treatment can be applied and see what the reaction is in them. In order to quantify and distinguish the changes that occur in the slabs, corrosion potential measurements were made.Once the measurements were made, for the old slabs the values of the corrosion potential measurements that were made when they were just made were necessary. This was possible thanks to the fact that these old slabs were part of a previous degree work and they were tabulated on it. Thanks to this, the changes made in the slabs could be distinguished. For the new slabs, a treatment known as MCI (Immigration Corrosion Inhibitors) was applied, and with the help of the measurements of the previous degree work, the differences that were presented in the short term were exposed.
