Precast prestresed concrete = Hormigón pretensado prefabricado

Abstract

[ENG]Prestressed concrete has been the latest great revolution in the building industry; it provided solutions to problems that could not be resolved with simply reinforced concrete or any of the other materials available at the time. It was soon related to long-line mass-production operations for economical reasons and the benefits of a controlled production environment. It provided engineers and architects the chance to design lighter and more resistant structures, allowing for higher quality materials to be used and being these more efficiently applied. This report lays down the principles for the design, production and reception of precast-prestressed products for the building industry. From the history of its development, mainly by the work of the brilliant French engineer Eugene Freyssinet, to the relevance given to prestressed-prefabricated products by the latest national and European standards
