Title : The elemental analysis of granulated blast furnace slag using WDXRF for conformity as per the EN 197-1 International standard
Abstract:
Granulated blast furnace slag (S) Granulated blast furnace slag is made by rapid cooling of a slag melt of suitable composition, as obtained by smelting iron ore in a blast furnace and contains at least two-thirds by mass of glassy slag and possesses hydraulic properties when suitably activated. Granulated blast furnace slag shall consist of at least two-thirds by mass of the sum of calcium oxide (CaO), magnesium oxide (MgO) and silicon dioxide (SiO2). The remainder contains aluminium oxide (Al2O3) together with small amounts of other compounds. The ratio by mass (CaO + MgO)/(SiO2) shall exceed 1,0.
The WDXRF instrument was setup with the fusion calibration method for the accurate and precise oxide analysis of slag.
The slag needs to conform to the EN 197-1 International norm to be used as an extender in king CEMII Portland Slag cement , CEM III Blast Furnace cement and CEM V Composite cements.
In order to lower the carbon footprint and reduce CO2 the clinker produced is used to produce more extended cements.
The kiln is fired with alternative fuels to make clinker that is more cost effective.
The more alternative fuels used to make cement, the lower the carbon footprint X-ray fluorescence is used to show new ways of reducing CO2.
