    Desarrollo de hormigones con aglomerante cal-puzolana fina como material cementicio suplementario Development of concrete mixtures with fine lime-pozzolan binder as supplementary c... by Juan José Dopico, Fernando Martirena Hernandez, Robert L Day, Bernhard Middendorf, Matthias Gehrke, Lesday Martinez

    Published 2008-01-01
    “…<br>The very high concrete strength and durability achieved in high and ultra-high-performance concrete is associated with a very dense matrix, accomplished through the use of high volumes of very fine mineral additions, such as fly ash, silica-fume, metakaolin and ground quartz sand. The paper reports on a study where a finely ground lime-pozzolan binder (LPB) is used as active mineral addition in concrete. …”
