Abstract

Procedimiento para la fabricación de hormigón de escoria, para la valorización de un residuo industrial, en este caso la escoria originada en la industria del acero de horno de arco eléctrico, mediante su encapsulación en una matriz cerámica de un material compuesto como es el hormigón, empleándola como conglomerante hidráulico. El procedimiento consiste en sustituir una parte del cemento, que se aplica como conglomerante, por escoria de acero inoxidable, dadas sus características aglutinantes, en una cantidad de hasta un 25% total del cemento.#Dichas escorias son altamente abrasivas, lo que confiere al hormigón resultante una resistencia elevada al desgaste. Esta característica hace que el hormigón obtenido mediante este procedimiento resulte óptimo para la fabricación de estructuras tales como acrópodos, tetrápodos y/o cajones para relleno marino dispuestos como escolleras en abrigo del mar.
