1. Introduction. Steel slag (SS) is the main byproduct in the steel production process. The main chemical components of SS are CaO, SiO 2, Al 2 O 3, FeO and main mineral phases are dicalcium silicate (C 2 S) and tricalcium silicate (C 3 S), which are similar to cement [1], [2], [3].At present, Chinese annual crude steel output can reach more than 1 billion tons, and the output of SS ...

Steel slags (SSs) are usually classified according to the type of furnace in which they are produced. The properties of the slag depend on the type of process used to produce the crude steel, the cooling conditions of the slag and the valorisation process. In the primary process, crude steel is produced in two ways.

Following binder spraying, the second step was to spread slag aggregates (Fig. 2b). It was required to calibrate the aggregate spreader in accordance with ASTM D562413 [].It was noted that aggregates were applied at a rate of kg/m 2 (50 lbs./yd 2) in steel container and were weighed to confirm the actual aggregate application rate which is kg/m 2 (50 lbs./yd 2).

Steel slag is residue from the steelmaking process, made of minerals like silica, alumina and titanium from iron sand, and combinations of calcium and magnesium oxides. During the steelmaking process, slags float on top of the molten iron, forming a barrier against oxygen and maintaining the internal temperature.
