Abstract:
This study investigates the possibility of recycling the ferrochromium industrial wastesin the Mat region of Albania by introducing it as a substitute for conventional coarseaggregate, in road base construction and in concrete. The chemical composition and aggregateabrasion resistance tests were carried out for ferrochromium slag (FCS). Moreover thecompressive strength of concrete with FCS as coarse aggregate was investigated. The resultswere compared with those carried out with natural river aggregates (NRA) and crushed riveraggregate (CRA). Based on the results the abrasion resistance of FCS was (25% mass loss inthe Los Angeles abrasion test) the highest compared to those of the conventional specimens.The compressive strength of concrete produced with FCS was 24% higher than that of CRAspecimen. The data acquired from the tests showed that FCS could be conveniently used ascoarse aggregate in road base construction and higher compressive strength concretes.
