Mexico is celebrating two hundred years of independence. In commemoration a monument is being built in Mexico City. The more than 100m high monument consists of a slim structure made of quartz and stainless steel called “Estela de Luz”. It is one of the first projects in Mexico involving reinforced concrete where corrosion control was specified before construction. The integrity management of this structure considered threats of seismic and wind forces and corrosion. The tower stability relies on a large block of reinforced concrete immersed in a soil that has a high phreatic level most of the year. The soil and phreatic water contain chlorides and other corrosive substances that may compromise the basement integrity at medium and long terms. As a critical component for corrosion control an impressed current cathodic protection system was installed. The main structure of the tower is made of eight large stainless steel columns embedded in the reinforced concrete block at base of the tower. Stainless steel elements hold a wall made of quartz plates on two sides of the tower. A large number of high strength steel bolts held the steel elements together. Anti-corrosion coatings and a cathodic protection system were implemented in order to prevent galvanic currents between high strength steel bolts and the stainless steel elements and between the stainless steel columns and the steel reinforcing bars of the reinforced concrete block at the base of the monument.
