Abstract
The Pervouralsk Dinas Works has developed mullite-silica vibrocast concrete of grade MKRV. In developing this grade we took into account all positive and negative aspects of the service of the previously used mullite-corundum concrete grade MKV. As a consequence, the mechanical strength of the concrete was raised in the whole service temperature range, its open porosity decreased and, accordingly, its impregnation with slag and metal decreases, and its heat-insulating properties were improved.
