Carbon resistance of corundum concretes

Conclusions The resistance of the corundum concretes to carbon during direct interaction under the conditions of high temperature isothermal holding is quite high. After holding for a period of 120 h at 1580°C, the weight loss of the concrete specimens is insignificant (0.2–0.4%) without exception.Modifying the structure of the concretes using chromium oxide and a mixture of lignosulfonates makes it possible to reduce the weight loss in the carbon-bearing medium.Translated from Ogneupory, No. 4, pp. 11–15, April, 1988.
