摘要
The invention relates to a method that combines a workshop for prefabricating reinforced concrete elements and a steel works, including the complementary installations necessary for the production of a cementing material. The slag (3) produced in the metallurgical reactor (1) is thermometallurgically treated in liquid state in a second reactor known as the electric reduction furnace (4) in order to produce (i) a clinker (8) and (ii) a ferroalloy (7). The clinker (8) is brought into the production of the cement (12) by means of on-site grinding. Said clinker is used, as with the cement reinforcing bar produced by the steel works, in the production of prefabricated concrete products. The inventive method results in a significant upgrading of the slag from the steel works and produces an improvement in environmental conditions through reductions in primary resources, carbon dioxide emissions and disposal on land.
