Micro-Mechanical Properties of Slag Rim Formed in Cement-Slag System Evaluated by Nanoindentation Combined with SEM. [PDF]

Materials (Basel), 2022
Slag rim mainly consists of secondary precipitations such as C–S–H gel phase and hydrotalcite-like phase, which originate from the hydration of slag. In this paper, the micro-mechanical properties of slag rim were characterized by nanoindentation in combination with SEM. It was found that, compared to the C–S–H gel phase, slag rim showed about a 15 GPa

Effect of slags of different origins and the role of sulfur in slag on the hydration characteristics of cement-slag systems

Construction and Building Materials, 2022
The effect of slag of different origins (synthetic slag produced in the laboratory and commercial slag collected from different steel factories) with comparable chemical composition, amorphous content and particle size distribution, on the hydration characteristics of slag cement was investigated. In order to study the effect of sulfur in slag, a model

Slag Cleaning Equilibria in Iron Silicate Slag–Copper Systems [PDF]

Journal of Sustainable Metallurgy, 2019
In this study, the equilibrium distributions of selected trace elements between molten iron-saturated copper alloy and selected iron silicate slags were measured, and the effects of silica fluxing on them. In addition to the copper and iron main components of the system, trace elements like antimony, gallium, germanium, gold, indium, and silver were ...
