- Abstract
In this paper, the effects of high carbon ferrochrome slag as coarse aggregate on workability, compressive strength, modulus of elasticity under static compression,electric flux, long-term shrinkage and content of extractable heavy metal of concrete were investigated. The results indicate that serious risk on technology will not arise when regarding the high carbon ferrochrome slag as coarse aggregate in concrete from the perspective of volume stability and extractable heavy metal. Under the appropriate mix ratio, the high carbon ferrochrome slag, if acting as coarse aggregate, will not bring obvious adverse effects into concrete. Hence, it will be feasible to consider the high carbon ferrochrome slag as coarse aggregate of concrete from the technical point of view.
