Abstract: The valorisation of industrial by-products in civil engineering is an important sector to the extent that the products to be obtained are not subjected to rigorous quality standards. This work aims to study the possibility of recycling blast furnace slag (BFS) from the El Hadjar factory. These wastes were collected, crushed, and then extruded as grains to be employed in the mass of self-compacting sand concrete (SCSC) by partially replacing the natural sand volume with different percentages (5, 10, 15, 20, 25, and 30%). The properties in fresh state (mini-slump flow, V-funnel flow time, and bulk density) and hardened state (compressive strength) of the different SCSC mixes are analysed and compared with the control SCSC mix (CSCSC). The results show a decrease in fluidity of SCSC with increasing BFS waste content. However, by replacing 5% of natural sand with BFS waste, SCSC's compressive strength is increased by 15%. This study also ensures that reusing BFS wastes in SCSC gives a positive approach to reduce the cost of materials and solve some environmental problems.
