摘要:
A clinker grinding method using a phosphonated grinding additive, preferably an aminopolyphosphonate, in an amount generally smaller than 2 %. The additive may also be a binary system including a phosphonated additive and a conventional non-phosphonated grinding agent. The method may advantageously be used with any grinding technology, including tubular mills and roller presses.
摘要:
The invention concerns the use of sols of non-metals or metals, their oxides, hydroxides, oxihydrates and/or polymers thereof (e.g. hetero-polyacids) for reducing proneness to cracking during hardening of unhardened binder suspensions (such as fresh concrete, ready-mix) and for secondary treatment of binder suspensions (e.g. concrete) which have hardened.
摘要:
Un procédé pour la mouture de clinker est divulgé. Ce procédé requiert l'utilisation d'un additif de broyage phosphonaté. Cet additif est de préférence un aminopolyphosphonate utilisé dans une quantité généralement inférieure à 2 %. L'additif peut également être représenté par un système binaire comprenant un additif phosphonaté et un agent de mouture non-phosphonaté conventionnel. Le procédé peut être utilisé avantageusement en relation avec toute technologie de broyage incluant les broyeurs tubulaires et les presses à rouleaux.
