Abstract
Steel slag (SS) is an industrial product of steel making. It can be produced in either an electric arc furnace (EAF), of which steel is produced by melting scrap steel, or a basic oxygen furnace (BOF), of which iron is converted to steel. SS can be used in many fields such as soil improvement, agricultural fertilizer, asphalt concrete, road construction, as a part of concrete/mortar aggregate and as a part of cement. In the current article, a short review of the previous studies using SS as a part of cement in paste, mortar and concrete is conducted. The effects of SS on the fresh, hardened properties and durability of paste, mortar and concrete have been reviewed and summarized. Additionally, different additives and special curing conditions used to improve some properties of SS matrices have been briefed. (C) 2019 The Author. Published by Elsevier B.V.
