Preliminary Study of the Use of a Secondary Lead Smelting
In this work, the preliminary study about the use of secondary lead smelting slag (SLSS) as an addition to Portland cement is presented. SLSS is a waste from a Colombian secondary lead smelter. The chemical, physical and mineralogical characteristics of the raw materials were evaluated by X-ray fluorescence, particle size and X-ray diffraction.

Leaching of toxic elements from secondary alkaline lead
Jul 12, 2019· Secondary alkaline lead slag (SALS), generated during lead–acid batteries recycling, is a hazardous waste due to its high reactivity, solubility, and migration of toxic elements. After pulverization caused by storage under atmospheric condition for 30 days, the SALS was sieved and coarse fraction (+ 1 mm) was returned to the recycling process.

Supplementary Cementing Materials The Portland Cement
Slag Cement, formerly referred to as ground, granulated blast-furnace slag, is a glassy, granular material formed when molten, iron blast-furnace slag is rapidly chilled typically by water sprays or immersion in water and subsequently ground to cement fineness. Slag cement is hydraulic and can be added to cement as an SCM.
