Análisis del costo del ciclo de vida de inhibidores de corrosión para la protección de estructuras de hormigón armado

Abstract

Criteria such as (materials) endurance and lifeexpectancy, or (structural) endurance have a significant impact on the make-up of concrete. That is to say that design and use criteria a factors in determining concrete's useful life. Currently, more and more corrosion inhibitors are used to extend the useful life of a structure. This is analyzed in this paper using the predictive model found in Life-365 Service Life. To carry-out this study use of corrosion inhibitors was modeled and their performance based on a strategic analysis of a structures useful life of a structure taking into account factors such as humidity and salinity (meaning different microenvironments). The impact of the inhibitors in terms of initiating and propagation of corrosion will be compared using the Tuutti model. In this way, this paper's objective is to propose a methodology to evaluate the characteristics for concrete from design taking into account environmental and longevity factors.

Comparative assessment of corrosion of concrete reinforced with unprotected steel and hot-dip galvanized steel

“…In analytical models, the use of corrosion inhibitors for environments under action of chloride ion and carbon dioxide, exhibit optimum receptivity for increased failure time and safety of the reinforced concrete structure (Faustino, Brás & Ripper, 2015;Poursaee 2016). In addition to benefiting and extending the life of the concrete structure, the use of corrosion inhibitors reduces the cost of living over the life of the concrete structure (Amaya, 2016).…”
