Abstract:
The paper shows the constituents and technical properties of low calcium aluminate cement concretes with ultra dispersed mineral powders and different admixtures.In the heat treatment conditions the refractory low cement concretes easily develop the high mechanical strengths, due of the new mineralogical phases apparitions which have the role in the genesis of a dense and strengthened bonding matrix. But in case of the same type of concretes it is imperatively necessary the development of good strengths in the normal conditions hardening process, too. This goal is achieved by using of a judicious ratio of chemical bond and micronized powders.
