| Popis: | This paper concerns comprehensive experimental study to evaluate properties and environmental suitability of Electric Arc Furnace (EAF) steel slag as well as mechanical behaviour of concrete designed with 100% of EAF slag as aggregate. Several tests were carried out on samples of fresh and aged slag, as required by standard specifications. In addition, the leaching behaviour and the volumetric stability were investigated. Concrete mixtures were designed with aged slag as aggregate having a diameter up to 31.5 mm. The concrete mechanical properties were then compared with the properties of reference mixtures having only natural aggregates. The concrete with EAF slag showed mechanical properties compatible with their use in civil constructions (compressive strength 35–45 MPa and modulus of elasticity up to 46 GPa). |
