Abstract
In the current paper, the investigation of the strength of refractory concrete with SiO2 microdust is presented. The influence of the sintering temperature and the high temperature stream of combustion products is discussed. It is shown that the strength of the refractory concrete samples treated in the stream of combustion products depends on their preparation for working under such conditions. Due to a different degree of sintering the samples strength is not identical and decreases with the growth of sintering temperature.
