replacing aggregates with steel slag

replacing aggregates with steel slag

If steel slag aggregates are used in an asphalt mixture, its permanent deformation resistance will be improved (Ameri et al., 2013). This means that replacing the skeleton of coarse aggregates with steel slag aggregates could improve the rutting resistance of the mixture (Ameli et al., 2020). In this study, the replacement was done with coarse aggregate by steel slag for different proportions of 0%, 25%, 50%, 75% and 100% for a M30 grade of concrete is used for a water cement ratio of ...

steel slag aggregate were approximately 9% 16% higher than that of the control mixture. Additionally, when using BFSP, the compressive strengths of the samples with steel slag aggregate increased continuously, and the 28-day compressive strengths of the mixtures using the steel slag aggregate were approximately 39.1 43.9 MPa. It was concluded that replacing some percentage of coarse aggregate with steel slag enhances the strength. The results showed that replacing about 60 percent of steel slag aggregates for coarse aggregate and 40 percent of ecosand for fine aggregate will
