The aluminous cement is the compound, which by its hydration-hydrolysis, is involved in the hardening process of the refractory concretes, under normal condition, like the consequence of hydraulic binding. A high value of aluminous cement dosage in concrete is followed by the decrease of the maximum use temperature and the depreciation of the mechanical and structural characteristics for this refractory material. The refractory concretes are widely manufactured mainly by using a common values of aluminous cement dosage (~20%). Also, there is the trend to decrease the cement dosage, at to very low limits, even up to its remove in order to improve the quality and use properties for these products. This is possible with by substitution of the aluminous cement with admixtures which are capable to develop other binding forms, next to hydraulic one. The aim of the present paper is to present the utilization possibilities of the aluminous and siliceous powders like substituents of the aluminous cement which are able to develop other binding forms, different from the hydraulic one.
