Description	The use of industrial slag as supplementary cementitious materials (SCMs) is expected to positively enhance the performance of concrete mixtures. Nowadays, it is imperious to qualify and implement such mixtures in practice, if the required specifications of their intended application are met. This investigation presents the results of a laboratory study of self-compacting concrete (SCC) containing high-volume replacement of industrial slag. Five mixes were prepared for different replacement percentage of slag and for varying strength between 20–100 MPa. The fresh and hardened concrete properties were measured. As expected, the inclusion of the industrial slag affected both freshened and hardened the concrete properties. The results illustrate that the demand for high-range water-reducing admixture decreases as the replacement percentage of slag increases. Analysis of the experimental data indicated that inclusion of industrial slag increased the strength. The addition of industrial slag to mixes also showed a consistent increment in strength starting from 3 days up to 90 days. The compressive strengths determined for the SCCs demonstrate that high-strength SCC of more than 100 MPa can be grasped by utilising slag appropriately. The results also indicate that SCC with up to 90% replacement by slag can successfully be used. Book Name: Circular Economy in the Construction Industry
