Popis:	The properties of traditional refractory concrete modified by means of microsilica and the deflocculant, including the different types of chamotte filler are studied. It is established that refractory concrete with chamotte filler Bos145 (containing 44% of has lower open porosity, and both high density and ultimate strength in compression compared with the properties of concrete with fillers Bos125 and Bos135 (containing ~26 and ~37 % Al2O3 respectively). It is also established that that independent of the type of chamotte filler supplementary addition of SiO2-based additive facilitates an increase concrete alkaline resistance by a factor of five and more. It is shown that this additive is effective at temperatures up to 1100°C, and at 1200 °C chamotte concrete porosity increases and the material resistance to molten alkali falls significantly.
