The great hardness of steel slag has led to it being considered as an aggregate in concrete. Many studies have been conducted to explore this possibility. In [8], steel slag was used to replace part of a fine aggregate fraction, in which silica sand (amounting to 15%, 30%, or 50%) or fine fraction was completely replaced by slag. In all the ...
