Two types of refractory concrete were prepared: first group of samples containing corundum and calcium-aluminate cement, and second group containing bauxite, calcium-aluminate cement (CAC) and chamotte. Each group of samples was prepared in 3 different variations: without admixture, with admixture and with silica fume as additive. Samples were dried at 110ºC, and afterwards heat-treated at 110, 800, 1300 and 1500ºC. Porosity was investigated using program for image analysis (Image Pro Plus) and, afterwards, effect of porosity on the mechanical properties (cold strength, strength at high temperatures, etc.) was observed. It was noticed that corundum concrete shows better characteristics than bauxite concrete. It is caused by pores and pore-size distribution, and also due to the formation of new mineral phases.
