Використання відходів металургійної промисловості для отримання жаростійких бетонів

Abstract

The need of the construction industry in the development and application of building materials with high physical and mechanical characteristics can be metthrough the use of cheap waste from the metallurgical industry – blast furnace ground and granulated slags. 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 heatresistant 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.
