PREPARATION FOR REFRACTORY CONCRETE, REFRACTORY CONCRETE AND METHOD FOR MAKING SAME

摘要

The present invention relates to a hydraulic binder for low-cement content concrete. The ground mineral portion of this cement comprises an under-calcinated alumina the BET specific surface of which ranges between 8 m2/g and 20 m2/g. Said binder enables to formulate a concrete the use properties of which remain stable and constant whatever the type of silica fume used, and capable of being used over a wide working temperature range for implementation. The invention also relates to a preparation for refractory concrete, a refractory concrete and a method for making a refractory concrete.
