Durability of concrete with electric arc furnace slag aggregate
Highlights Durability of EAF concretes under different exposure conditions up 3 years is studied. Concretes with EAF slag and equivalent mixes with limestone or barite were compared. Experimental investigation and microstructure of long-term properties were examined. The use of EAF as an aggregate for concrete production must be carefully monitored.
Abstract The durability of concrete mixes with EAF slag as aggregate (HS) is studied; mixes with limestone (HC) and barite (HAB) aggregates were used as reference for structural and heavy-weight applications, respectively. Compressive strength, elastic modulus, water penetration under pressure, wet-dry cycles, freeze-thaw cycles, influence of environmental condition and leaching tests were conducted. The results indicate that HS tends to present higher depth of water penetration under pressure, a slightly higher expansion, higher carbonation depth and similar compressive strength than reference HC. Should be payed attention to the formation of stain points on HS concrete surface subjected to wet-drying cycles.
