“…Implementing the research programme, it was necessary to mind that applied components must be cheap and accessible for producers. It is known (Robson 1967;Clavaud et al 1985;Montgomery 2003;Hewlett 2004) that, for producing refractory concrete with working temperature of over 800-900°С, use of CAC or liquid glass as a binder, and chamot, high alumina burnt clay, cordierite, mullite, corundum and other components as aggregate, is necessary. However, the cost of the above components is much higher than those selected for this research.…”
