Вогнетривкі бетони на цементах із залізовмісними шлаками

Abstract

The possibility of using blast furnace slag as aggre- gates for the production of heat-resistant concrete is based on the fact that when heated to a temperature of 800° C, the slags has a higher strength than Portland cement and traditional fillers. At the same time, slag aggregates are 1.2–2 times cheaper than natural ones and require significantly lower financial costs. The use of slag aggregates for the production of heat-resistant concretes will make it possible to produce heat-resistant structures with high operational characteristics. The use of metallurgical waste in the form of blast furnace slag improves the environmental situation.
