Cementos especiales. Efecto de aditivos

Abstract

La necesidad a nivel mundial y especialmente a nivel europeo y nacional de reducir el consumo de energía y las emisiones de gases causantes del efecto invernadero en la fabricación del cemento ha conducido a la búsqueda de nuevos cementos más ecoeficientes, como los cementos de escoria activada alcalinamente. Estos cementos, morteros y hormigones alcalinos presentan destacadas ventajas con respecto a los correspondientes de cemento Portland, como elevadas propiedades mecánicas iniciales, bajo calor de hidratación y buena durabilidad frente a ácidos, agua de mar o sulfatos. Sin embargo, estos materiales presentan dos principales problemas desde el punto de vista tecnológico cuando se emplea una disolución de waterglass como activador alcalino como una retracción hasta cuatro veces superior a la del cemento Portland así como fraguados no controlados.

El Instituto de Ciencias de la Construcción Eduardo Torroja (CSIC) organiza seminarios monográficos sobre temas de actualidad en el ámbito de la Tecnología de la Construcción y de sus Materiales a cargo de destacados investigadores nacionales y extranjeros del sector.
