“…Rapid hardening, corrosion resistance (to acid environment) and high temperature resistance characterizes this material from limestone and bauxite [3]. We can recognize two possible ways for its production: burning to the sintering (1250 °C -1350 °C) and grinding [4,5] or melting of input raw materials (mixture of bauxite and limestone) at 1600 °C in electric arc furnace. Slow cooling of melt ensures crystalline CA (CaO•Al 2 O 3 ); aluminous cement is produced by grinding of cooled CA.…”

This contribution brings summary of refractory hydraulic binder issue. The refractory cement composites (or refractory concrete) represent very specific area of modern material engineering. We can find its use in special monolithic structures in industry, for fire-resistance brick, protection cladding, etc. The composition brings opportunity for using aluminous cement with different amount of Al2O3, according to temperature level. Hydration process and products together with the decomposition due high temperatures is described in this paper. Also the risk of conversion metastable hydration to stable one is described. The issue of possible bonds between filler and binder is shown (hydraulic, ceramic and chemical). Paper also describes values of fracture energy of aluminous cement pastes with various water to cement ratio after temperature loading.
