Liquid slag produced in a blast furnace BFis at a temperature of around 1500?C and has a sensible heat of around 400Mcalton. BF slag is rich in CaO SiO2 Al2O3 and MgO which are similar to the components of Portland cement. When this liquid BF slag is cooled fast enough then the solidified slag has a large percentage of glassy phase with high cementations activity and hence it can be used ...

Nov 25 2018 Uses of BF slag. Uses of BF slag which have been developed date back many centuries. BF slag has been used in road building as long ago as in the year 1830 and as railroad ballast since the year 1875. The use of BF slag as concrete aggregate began in the year 1880 and in bituminous surfaces in the early 1900s.
Nowadays blended hydraulic-slag BF slag cements CEM IIAB-S and CEM III are commonly used in several countries in Central and Northern Europe although their applications in concrete engineering structures are rare Giergiczny et al. 2009. Only the grounded granulated BF slag can be used as a partial Portland cement replacement.
