Steel slag waste is a by-product of steel mining industry. Effort to utilize the steel slag in concrete production has been failed due to its high contents of MgO which causes volumetric instability of the hardened concrete. Researchers also have failed to utilize the steel slag in the sub-base of road construction due to its low compaction ratio.

Preparation microstructure and property of carbonated
The carbonated artificial steel slag aggregates owned bulk densities of 1230–1300 kg/m 3 and crushing values of 15.68–22.48%. 2 The carbonated artificial steel slag aggregate showed a very stable volume after the autoclaving test at an elevated temperature of 216 C.
Effect of Steel Slag and Portland Cement in the Rate of
It is concluded that the steel slag can be used as an activator of GGBS and the optimum composition of those materials was determined with a proposed parameter called “slag index.” The properties measured in blended OPC-GGBS-BOS mixes showed encouraging results to be used industrially.
Slag Aggregate - an overview ScienceDirect Topics
The study confirms the viability of producing steel-reinforced concrete with slag aggregate Arribas Vegas San-Jose and Manso 2014 . Other researchers Brand and Roesler 2015 also confirmed that steel slag aggregates in concrete can produce acceptable strength properties suitable freeze–thaw durability and exceptional fracture properties.
Preparation microstructure and property of carbonated
Carbonated artificial steel slag aggregates were prepared via carbonation. Calcium carbonates were the main binders in the artificial steel slag aggregates. The artificial steel slag aggregate had light weight and stable volume. Concrete with artificial aggregates gained compressive strength of 45.5 MPa at 28d
