Reuse Opportunities for Electric Steel Mill Slag in Morocco's Road-Building Sector

摘要

Road construction and maintenance require tremendous quantities of aggregates. The relatively restrictive nature of road-building specifications limits the range of materials commonly used to certain categories, including alluvial deposits in the wadi ravines typical of Morocco and materials stemming from massive rocky outcroppings. The increasing scarcity of road-building materials now affecting various regions throughout the country (e.g. the El Jadida province), combined with the rising cost of transport and greater attention paid to environmental problems, has led the administration, corporate sector, research laboratories and all relevant technical bodies to seek mitigation strategies, more specifically through reliance on techniques that reuse locally available materials or materials originating from an industrial source, as is the case with electric steel mill slag.%StraBenbau In diesem Artikel werden Techniken zur Wiederverwendung von vor Ort verfügbaren Materialien aus der Industrie beschrieben, beispielweise Schlacke aus Elektrostahlwerken für den StraBenbau.
