CIMENTURI HIBRIDE ALCALINE. PARTEA a III-a - DURABILITATE ŞI APLICAŢII INDUSTRIALE ▲ HYBRID ALKALINE CEMENTS. PART III. DURABILITY AND INDUSTRIAL APPLICATIONS

This part of the research explored the reaction of hybrid alkaline cements when they are exposed to acid (0.1N HCl), sulphates and seawater. The hybrid cement used in the experiments comprised essentially metallurgical slag generated by the Fe and Zn industries. A standard Portland cement was used as the reference system. The findings showed that performance of these hybrid cements was similar to the results observed for the control. In a subsequent industrial trial, the concrete made with this experimental binder was successfully used in the manufacture of precast blocks and pavers. Lucrarea prezintă rezultatele cercetărilor privind comportarea cimenturilor alcaline hibride in soluţii agressive acide (HCl 0,1N), cu sulfaţi si apă de mare. Cimenturile hibride utilizate in cadrul experimentărilor conţin zguri rezultate din metalurgia Fe si Zn. Cimentul portland standard este folosit ca sistem de referinţă. Rezultatele au arătat că aceste cimenturi hibride au avut performanţe asemănătoare cu cele observate pentru cimentul de referinţă. Intr-un studiu ulterior, efectuat la nivel industrial, s-a constatat că betonul realizat cu acest liant hibrid a fost folosit cu succes la fabricarea de blocuri prefabricate si pavele.
