Abstract

Στο παρόν περιγράφονται νέα τσιμεντοκονιάματα με υψηλό βαθμό ρευστότητας και σύντομους χρόνους στερεοποίησης. Τα κονιάματα περιέχουν νερό, ένα ταχύπηκτο τσιμέντο, ρευστοποιητές ή/και υπερρευστοποιητές, ρυθμιστές πήξης και αδρανή υλικά με ειδική κοκκομετρική κατανομή. Τα συσσωματώματα αποτελούνται από δύο κλάσματα με διαφορετικό μέγεθος κόκκων, έτσι ώστε η αναλογία μεταξύ των χαρακτηριστικών διαμέτρων κόκκων των δύο κλασμάτων να κυμαίνεται μεταξύ 2,2 και 3,2. Τα νέα κονιάματα που λαμβάνονται με αυτόν τον τρόπο έχουν τιμές ρευστότητας 2-3 φορές υψηλότερες από εκείνες των κονιαμάτων που παράγονται με τα παραδοσιακά συσσωματώματα. Η αύξηση στη ρευστότητα επιτυγχάνεται χωρίς αύξηση της αναλογίας νερού / τσιμέντου και χωρίς αύξηση της ποσότητας των υπαρχόντων ρευστοποιητών. Το κονίαμα που παράγεται σύμφωνα με την εφεύρεση μπορεί να χρησιμοποιηθεί προς όφελος όλων των εφαρμογών στις οποίες απαιτείται να συνδεθεί ένας υψηλός βαθμός ρευστότητας και μια ταχεία στερεοποίηση.
