Strength And Stability Of Concrete Samples Produced With Electric Arc Furnace Slag

This research investigated the hardened properties of concrete specimens produced with electric arc furnace (EAF) slag as aggregate. The concrete mix proportions were calculated following the Densified Mixture Design Algorithm (DMDA) method with various water-to-binder (w/b) ratios at 0.3,0.4 and 0....

Summary:This research investigated the hardened properties of concrete specimens produced with electric arc furnace (EAF) slag as aggregate. The concrete mix proportions were calculated following the Densified Mixture Design Algorithm (DMDA) method with various water-to-binder (w/b) ratios at 0.3,0.4 and 0.5. To examine the hardened characteristics, the strength development including compressive strength, splitting tensile strength, and ultrasonic pulse velocity (UPV) tests were conducted, while the expansion under autoclave conditions was observed to the stability of concrete samples. The concrete specimens exhibited a compressive strength range of 19.1-57.9 MPa and splitting tensile strength of 1.76-3.82 MPa at 28-day, significantly reducing with increasing w/b ratio. The UPV results were higher than 3660m/s, while the concrete samples were stable in shape under the autoclave condition test.
