Evaluating potential expansion and strength of compacted steel slag aggregates at different compaction density

Abstract Steel slag aggregates can be utilized as unbound materials for road bases or fine/coarse in asphalt/cement paving concrete. However, the availability of free lime (f-CaO) is detrimental to volumetric stability, affecting strength durability resulting products incorporating steel aggregates. This paper investigates potential expansion fine and coarse compacted at different compaction densities. The experimental results exhibited a higher stability granular mixture exposed water than one. Also, more increased expansibility mix, especially high density. Furthermore, graded aggregate other findings provide reference information on useability cement-based materials, like replacement better ones volume
