The use of reinforced concrete at La Sagrada Família should come as no surprise, as Gaudí had provided for it. He was one of the first architects to use the material because Eusebi Güell was the owner of the first Portland cement factory in the country, at Castellar de n'Hug.
At La Sagrada Família we can find reinforced concrete on the terminations of the towers of the Nativity façade, built directly by Gaudí, who also proposed to use it on the construction of the naves to concentrate the horizontal forces on the columns and reduce the amount of scaffolding for the construction.
Since current regulations have enormously increased the requirements and the impositions now demanded from a structure, at La Sagrada Família the number of armatures, the qualities and the bearing capacity of the concrete have had to grow in a similar proportion, while maintaining the sections and the slenderness of Gaudí's original design.
