calcite is transformed into lime CaO at 850°C (and also up to 1200°C), yet participates in the formation of glass at °C and 1800°C. The presence of lime CaO is not recommended in any geopolymeric sytems because it generates flash setting (fast hardening).

· There, the elements solidify into slag that includes nonmetallic elements, such as oxides of aluminum, silicon and calcium oxides; and that may also pull nitrogen, hydrogen and some carbon out with it. The flux inside of both gas and selfshielded fluxcored wire impacts the way slag behaves. For example, wires with higher levels of titanium dioxide (TiO2) have faster .
Slag is a byproduct of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (byproducts of processing iron and steel), ferroalloy (byproduct of ferroalloy production) or nonferrous/base metals (byproducts of recovering nonferrous materials like copper, nickel, zinc and phosphorus). Within these general egories, slags can be further .

• There are no convection currents in the capillary. This is achieved through maintaining a temperature gradient, and placing the densest slag in the capillary. The 'effective diffusion coefficient' for each diffusing species was determined by applying Equation [1] to the experimental data using a nonlinear fitting routine. The flux of each species was calculated using the effective dif
In any event, slag reactivity is largely described by a parameter known as degree of polymerisation (DP, see Eq. ) (10, 51). Its value normally ranges from : the higher the value, the greater the degree of polymerisation and consequently the higher slag reactivity .
