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.

Utilization of secondary lead slag as construction material -

2005. 6. 1.  Secondary lead slag, a waste product from battery smelting using CaCO 3 as flux, has been investigated for its use as an admixture and/or aggregate in the production of concrete blocks. The slag was added as partial replacements of cement and/or aggregate. The results revealed that the oxide components of the slag were similar to those of ordinary Portland cement (OPC). The CaO content in the slag

A review on lead slag generation, characteristics, and

2019. 7. 1.  The secondary lead slag has been used in a cement-based stabilization/solidification process for the preparation of concrete (Cioffi et al., 2000). The addition of up to 30% of lead slag did not affect the hydration chemistry of the binder. The unconfined compressive strength of the produced concrete blocks was 23–25.6 MPa.

Lead Slag - an overview ScienceDirect Topics

Due to the lack of aluminum in the lead slag, the addition of FA as a secondary aluminum source was shown to be effective; an optimum lead slag/FA ratio of 70/30 was reported, yielding a compressive strength of 47 MPa after sealed curing, increased density and reduced water absorption. 56 These cements immobilized Pb most likely via incorporation in the main aluminosilicate binding phase, as

Leaching of toxic elements from secondary alkaline lead

2019. 7. 12.  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.

Concrete performance using BFS cement - Article on the

2006. 11. 1.  In laboratory tests ordinary concretes with high slag blastfurnace cements lead to a higher scaling in the first freeze-thaw cycles than Portland cement. This scaling ranges between 0.1 to 0.3mm cement grout from the surface. Afterwards the scaling rate decreases significantly. HPC with high slag blastfurnace cement does not show this effect.
