Abstract

In this paper, in order to improve the utilization of metallurgical steel slag, the strength and water resistance of magnesium sulfide cement foam concrete with metallurgical steel slag as admixture were studied. The hydration products were characterized by scanning electron microscope (SEM). The results show that the structure of magnesium sulfide cement foamed concrete is more compact, the strength is not lost, the water resistance is improved to a certain extent, and the cracking of foamed concrete is inhibited to a certain extent by the appropriate amount of metallurgical steel slag.

Keywords

steel slag; magnesium oxysulfate cement; compressive strength; water resistance; thermal conductivity
