Characteristics of Mortars with Blast Furnace Slag Powder

Recently, interest in environmentally friendly development has increased worldwide, especially in the construction industry. In this study, blast furnace slag powder (BFSP) and mixed steel fine aggregates were applied to cement mortars to reduce the environmental damage caused by the extraction of natural aggregate and to increase the recycling rate of steel by-products in the construction

2018-9-1  Use of BOF slag powder as supplementary cementitious materials. The calcium silicate phases in BOF slag could provide potential cementitious properties. However, the reactivity of C 3 S and β-C 2 S in BOF slag is relatively low, probably due to the dense structure and large crystal size formed at a higher temperature (∼1600 °C).

Steel Slag an overview ScienceDirect Topics

Air-cooled steel slag may consist of big lumps and some powder. The mineral composition of cooled steel slag varies and is related to the forming process and chemical composition. Air-cooled steel slag is composed of 2CaO · SiO 2, 3CaO · SiO 2 and mixed crystals of MgO, FeO, and MnO (ie, MgO · MnO · FeO), which can be expressed as RO phase

Steelmaking Slag an overview ScienceDirect Topics

2012-4-4  D. Sichen, in Fundamentals of Metallurgy, 2005 9.5.1 Slag–metal mixing. In steelmaking, slag–metal mixing is a very common phenomenon and it occurs due to the shear at the slag–metal interface caused by excessive liquid steel flow. 37 This mixing leads to emulsification of steel in slag, which increases the total interfacial area and consequently the rate of slag–metal reactions.
