Recently, with increasingly stringent environmental regulations and the depletion of natural aggregate resources, high-quality aggregates have become scarce. Therefore, significant efforts have been devoted by the construction industry to improve the quality of concrete and achieve sustainable development by utilizing industrial by-products and developing alternative aggregates. In this study, we use amorphous metallic fibers (AMFs) to enhance the performance of mortar with steel slag aggregate. Testing revealed that the 28-day compressive strength of the sample with steel slag aggregate and AMFs was in the range of 48.7-50.8 MPa, which was equivalent to or higher than that of the control sample (48.7 MPa). The AMFs had a remarkable effect on improving the tensile strength of the mortar regardless of the use of natural aggregates. With AMFs, the drying shrinkage reduction rate of the sample with 100% steel slag aggregate was relatively higher than that of the sample with 50% natural fine aggregate. Furthermore, the difference in the drying shrinkage with respect to the amount of AMFs was insignificant. The findings can contribute to sustainable development in the construction industry.

The growing demand for sustainable infrastructure has increased interest in eco-friendly design solutions such as porous asphalt (PA) pavements, which manage stormwater runoff and mitigate urban heat islands, and warm mix asphalt (WMA), which reduces energy consumption and emissions during production. This study evaluates the mechanical and environmental performance of four warm mix porous asphalt (WPA) mixtures incorporating recycled materials and by-products: reclaimed asphalt pavement (RAP), aramid pulp fibres, and electric arc furnace (EAF) steel slag. A Life Cycle Assessment (LCA) with a cradle-to-cradle approach was conducted to comprehensively assess environmental impacts.

The modern metallurgical industry produces approximately 90% of the volume of all produced steel; for this, integrated technology based on fossil materials such as coal, fluxes, and especially iron ore is used. This industry generates large amounts of waste and by-products at almost all stages of production. Alternative iron and steel production technologies based on iron ore, methane, or pure hydrogen are also not waste-free.

Industrial solid wastes like coal fly ash (CFA) and steel slag pose environmental challenges, while the remediation of heavy metal-contaminated water remains a global priority. This study investigates the impact of incorporating steel slag during the synthesis of CFA-based geopolymers (CFAG) on the leaching characteristics of inherent heavy metals in CFA and the Zn adsorption performance of CFAG. Leaching experiments show geopolymerization effectively immobilizes heavy metals including Fe, Cr, As, Cd, and Ti in CFA while having little effect on Mn, V, and Ni.
