In Italy, in 2020, the production of slag from electric arc furnace (EAF) has been estimated in about 3 million tons, with disposal rates in landfills still around 45–50%. Due to their characteristics, steelmaking slags represent a valid alternative to the natural materials commonly used, especially in the construction sector. Therefore, the aim of this work is to analyse the behavior of concrete mixtures with the addition of different percentages (0, 10, 25 and 50%) of EAF slag, evaluating both rheological and strength properties over time. The results of the tests showed that the use of EAF slag for the production of ordinary concrete is possible as rheological and mechanical properties are maintained and/or improved.

Abstract
In Italy, in 2020, the production of slag from electric arc furnace (EAF) has been estimated in about 3 million tons, with disposal rates in landfills still around 45–50%. Due to their characteristics, steelmaking slags represent a valid alternative to the natural materials commonly used, especially in the construction sector. Therefore, the aim of this work is to analyse the behavior of concrete mixtures with the addition of different percentages (0, 10, 25 and 50%) of EAF slag, evaluating both rheological and strength properties over time. The results of the tests showed that the use of EAF slag for the production of ordinary concrete is possible as rheological and mechanical properties are maintained and/or improved.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
