Reactivity Alteration of Granulated Blast Furnace Slag by
· Augmenting granulated blast furnace slag (GBFS) content in Portland Slag Cement (PSC) beyond the conventional limit of 70 is the stimulus for this study. Such enhancement other than bringing down the carbon footprint of cement conserves natural resources. However beyond 70 slag incorporation early strength gain of PSC is meagre because of its low reactivity.

Carbothermic Reduction of Ilmenite Concentrate with Coke
The electric arc furnace process is a common method to produce high TiO 2 slag from ilmenite. The pre-reduction process was proposed in recent years in order to reduce electricity consumption. In order to enhance the pre-reduction degree high energy ball milling was proposed to improve the specific surface area of the ilmenite prior to reduction.

PCA effect on structure of fly ashes and slag
Abstract In this study we have modified slag and fly ashes by mechanosynthesis process carried out by high-energy ball milling using a planetary mill. In order to optimize the milling conditions we have added process control agent (PCA). This PCA affects powders agglomeration phenomena during milling and impacts the milling time for the final product.
