This study was conducted to investigate the effect of ground granulated blast furnace slag on the structural performance of precast concrete beams, evaluating the flexural, shear and bonding performance by using the replacement ratio of the ground granulated blast furnace slag as a variable. The design strength of the concrete was set at 45 MPa in …

The activity of slag and the base used decide the basic performances of this kind of material. In this study, granulated blast-furnace slag was treated by wet grinding to promote its reactivity (i.e. WGGBS), and carbide slag (CS), one kind …

Ground granulated blast-furnace slag (GGBFS) is mainly consisting of CaO, SiO 2 and Al 2 O 3. In recent decades, the use of GGBFS as an alternative binding material (alkali-activated slag, AAS) and partial replacement of cement has increased, .

Grinding of granulated blast furnace slag was only done domestically by cement companies. Supply constraints appear to have limited domestic consumption of GGBFS in recent years. Although prices have increased, sales of GGBFS have not correlated with the increases in the quantity of cement sold since

Granulated Blast Furnace Slag (GBFS) contains a high level of moisture, it is hard to grind and very abrasive. 2 Natural pozzolans may not be as hard to grind as GBFS but may contain high moisture levels and be abrasive. 2 Both of these materials require grinding systems designed to deal with high moisture, hardness and abrasiveness.
