EL SECRETO DEL ANTIGUO HORMIG\u00d3N ROMANO\u00a0<\/h2>[\/et_pb_text][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”]

Aunque las construcciones modernas de hormig\u00f3n se desmoronan al cabo de unas pocas d\u00e9cadas, sobre si est\u00e1n situadas cerca de ambientes marinos, las antiguas estructuras romanas, no solo se mantienen en pie, sino que son incluso m\u00e1s estables y fuertes que cuando se construyeron. \u00bfPero cu\u00e1l es el secreto? Los investigadores han descubierto que el agua de mar que se filtra a trav\u00e9s de la estructura microsc\u00f3pica de este hormig\u00f3n, origina el crecimiento de una serie de minerales que aportan una dureza a\u00f1adida a estas antiguas construcciones.<\/p>\n

Los romanos fabricaban su hormig\u00f3n mezclando cenizas volc\u00e1nicas, cal y agua de mar, para hacer su mortero y despu\u00e9s incorporaban roca volc\u00e1nica. Esta mezcla produce una reacci\u00f3n llamada puzzol\u00e1nica, en homenaje a la ciudad de Pozzuoli en la bah\u00eda de N\u00e1poles, y se utilizaba sistem\u00e1ticamente en muchas de las construcciones, como por ejemplo, las grandes estructuras que proteg\u00edan los puertos.<\/p>[\/et_pb_text][et_pb_image src=”https:\/\/olgapayan.com\/wp-content\/uploads\/2025\/03\/hormigonromano1_fe46605f.jpeg” title_text=”hormigonromano1_fe46605f” align=”center” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” text_font_size=”14px” global_colors_info=”{}”]

Perforaci\u00f3n en una antigua estructura romana. Proyecto ROMACONS<\/p>[\/et_pb_text][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”]

En la actualidad al cemento Portland se le a\u00f1aden agregados que deben reaccionar expandi\u00e9ndose y desquebrajando el hormig\u00f3n y destruyendo la mayor\u00eda de estructuras modernas, pero la realidad es que estos agregados terminan por facilitar la aparici\u00f3n de grietas que se van propagando por todo el material.<\/p>\n

Un estudio recogido por el proyecto ROMACONS identifica, en el hormig\u00f3n romano, unos minerales excepcionalmente raros: la tobermorita aluminosa y la phillipsita. Concluyeron que el agua del mar se introduc\u00eda en la estructura, disolviendo los componentes de la ceniza volc\u00e1nica, permitiendo el crecimiento de cristales de estos minerales, muy similares a los que se forman en las rocas volc\u00e1nicas, y que aumentan la resistencia del hormig\u00f3n a la fractura. Este es un proceso similar a la corrosi\u00f3n, que en cambio ser\u00eda muy perjudicial en los materiales m\u00e1s modernos.<\/p>\n

Desgraciadamente, aunque se han estudiado los antiguos textos romanos, la receta no se conoce y no somos capaces de recrear los m\u00e9todos y mezclas para conocer de manera precisa todas sus reacciones qu\u00edmicas y producir este tipo de hormig\u00f3n.<\/p>[\/et_pb_text][et_pb_video src=”https:\/\/www.youtube.com\/watch?v=ikH6Vmb0pog&embeds_referring_euri=https%3A%2F%2Fassesmentandpreservation.blogspot.com%2F&source_ve_path=Mjg2NjY” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_video][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”]
