On casual examination, GBFS would pass for river sand, with a top size of about 6mm. 2. The report covers key drivers and constraints for individual slag markets and end-users from the construction sector. When iron-ore, coke and limestone melt in the blast furnace, two products are produced—molten iron, and molten slag. Blast-furnaces are fed with controlled mixture of iron-ore, coke and limestone, and operated at a temperature of about 1,500°C. Ground Granu-lated Blast-Furnace Slag (GGBFS) is a glassy granu-lar material formed when molten blast-furnace slag is rapidlycooled,usuallybyimmersioninwater,andthen groundtoimproveitsreactivity.Themajorcomponents of blast-furnace slag are SiO2, CaO, MgO, and Al2O3, which are common components in commercial silicate glasses. ground granulated blast furnace slag on the composition and microstructure of the paste was analyzed by using XRD, SEM, EDS, and TG-DSC at di erent curing ages. 1. When mixed with water it will hydrate in a similar way to Portland cement. The ground blast furnace slag concrete is significantly more resistant to the diffusion of chlorine than the Portland Cement of the same grade. 453/2010 amending the former) Rev.
