Abstract
VALORIZATION OF ANNABA STEEL COMPLEX BLAST FURNACE SLAG IN CONCRETE PRODUCTION: A REVEW
Dr. Djamel Beggas*
ABSTRACT
Concrete is a fundamental construction material employed worldwide.Aggregates, along with cement and water, constitute the primaryconstituents of concrete, accounting for between 55% and 80% of itsvolume. These aggregates are either extracted from natural deposits orcrushed from larger rocks. Aggregate reserves are being rapidlydepleted as a result of the continued growth of the global constructionindustry, which is leading to significant annual increases in theconsumption of natural aggregates. Such a high use of naturalaggregates represents a serious environmental risk. For this reason, investigating the potentialof using waste materials and industrial by-products in concrete production is of a greatimportant. This approach offers alternatives substitutes for natural aggregates, leading tomore sustainable concrete and greener design. This work presents a comprehensive review ofusing Annaba blast furnace slag, considered an industrial waste, in the fabrication ofconcrete, with particular reference to using slag concrete as a filling material in lightweightsteel construction, highlighting its sustainability and environmental benefits. This studyreviews the existing literature on using slag in the concrete and cement industries. It assessesthe content and results of prior studies and presents the expected impact of these by-products.The aim is to assess and explore the potential for reuse of steel slags, which are difficult tostore and can be released into the environment. Both the economic and environmentalbenefits were investigated.
