The Al2O3–CaO–SiO2 ternary is a basic oxide system relevant for the Pedersen alumina production process and aluminothermic silicon with low environmental impact using secondary aluminium silica raw materials. Rheological property one of most important properties above applications. A phenomenological viscosity model, inspired by Calphad technique, has been proposed description rheological cover...

Ground granulated blast furnace slag (ggbs), can reduce the alkali load in concrete, despite its relatively high alkali content. Most research has been devoted to the efficacy of slag with an alkali content of less than 1.0% and this is reflected in guidance documents. A comparative assessment was made of the effect, if any, of the alkali level of ggbs on potential alkali-silica reactivity. Exp...

The objective of this study is to examine the effect of substitution of cement by three different mineral additions, on the mortar rheological and mechanical properties. This experimentation, considers the fineness of mineral additives with a constant workability. Ordinary Portland Cement was partially replaced by different percentages of slag, pozzolana and metakaolin of 10, 20 and 30%. The ob...

Copper smelting slag usually contains 1–6 wt% copper, which can be recovered by pyrometallurgical and flotation processes. However, the tailing slags still consist of 0.3–0.7 Cu 35–45 Fe equivalents to those in copper iron ores, respectively. Most research was focused on recovery from slags. increase mechanical strength, corrosion resistance antibacterial property some steels. A new process rec...

Thermodynamic data of chromium oxide activities in molten slags are important for improvement the reduction treatment process oxides stainless steel slags. The chemical equilibrium experiments were conducted present work to measure activity coefficients CaO-CaF2-MgO-Al2O3-SiO2-MnO-CrOx at 1823 K (1550°C) under oxygen partial pressure 2.57×10-11 atm with different contents. It is found that no s...
