Abstract

Επιταχυντής πήξεως και σκληρύνσεως υδραυλικών συνδετικών υλικών που περιλαμβάνει τις ακόλουθες αναλογίες κατά μάζα: από 25 έως 35 τοις εκατό εξ ενός τουλάχιστον σουλφοαργιλικού κλίνκερ, από 45 έως 55 τοις εκατό εκ μίας τουλάχιστον πηγής θειικών αλάτων που έχει διαλυτότητα μεγαλύτερη από 4 g.L[-1] εντός ύδατος στους 20 βαθμούς Κελσίου, και από 10 έως 20 τοις εκατό εκ μιας τουλάχιστον πηγής θειικών αλάτων που έχει διαλυτότητα μικρότερη από 4 g.[L-1] εντός ύδατος στους 20 βαθμούς Κελσίου, όπου το εν λόγω κλίνκερ περιέχει ορυκτολογικές ενώσεις του τύπου αργιλικών αλάτων ασβεστίου. Η σύνθεση τσιμέντου η οποία περιέχει τον εν λόγω επιταχυντή πήξεως και σκληρύνσεως μπορεί να υλοποιηθεί σε θερμοκρασίες κυμαινόμενες από 5 βαθμούς Κελσίου έως 35 βαθμούς Κελσίου, και να χρησιμοποιηθεί προκειμένου να ληφθεί ένα εκτοξευόμενο σκυρόδεμα, ή ένα κονίαμα σφραγίσεως ή σφηνώσεως που έχει βελτιωμένες μηχανικές αντοχές σε θλίψη.
