Slag fuming is a process of extracting zinc from molten slag in the form of metal vapor by injecting or adding a reducing source such as pulverized or lump coal, natural gas, etc. Top Submerged Lance (TSL) technology has been successfully applied to extract zinc by a fuming process from residues from the zinc industry, ISF and QSL slag and Lead blast furnace slag. A Computational Fluid Dynamic ...

Abstract The paper presents the correlation between flexural strength and modulus of elasticity with respect to compressive ternary concrete (TC), made by incorporating Micro silica (5% 15%) Ground granulated blast furnace slag (20% 50%) considering w/b=0.55. A total twelve mixes one conventional mix were prepared identify optimum mix. Flow characteristics properties (compression, rupture elast...

This work presents a novel way to examine the characteristics of fly ash, copper slag (CPS) along with addition Ultrafine Ground Granulated Blast Furnace Slag (UFGGBFS) based Geopolymer Concrete (GPC) for various molarities (10M, 12M and 14M). In GPC, ash was replaced UFGGBFS (5 %, 10 % 15 %) used as fine aggregate. Mechanical Characterization such split tensile, flexural strength, workability ...

This article presents a combined use of a retarder (d-gluconic acid) and an alkaline activator (sodium hydroxide) in a binder system based on ground granulated blast-furnace slag. The properties of the retarder are extending the dormant hydration period and suppressing the generation of strength-giving phases. Different retarder concentrations between 0.25 and 1.00 wt.% regulate the intensity a...

This paper focuses on research concerning the ecotoxicological properties of granulated slag from the pilot production of gray iron with red mud addition and concrete composites with the application of this slag. Red mud is a hazardous waste generated in the production of aluminium oxide. Negative ecotoxicological tests are, therefore, one of the basic prerequisites for the ability to use granu...

An effective retarded suspension of ground granulated blast-furnace slag (GGBFS) needs a strong activator to reactivate the hydration. In this research study, sodium hydroxide (NaOH) as an alkali activator in two different concentrations (30 and 50 wt.%) was used to overcome the retardation and give the hardened GGBFS the reasonable strength. The study was carried out with a mixture of GGBFS, a...

The poor abrasion resistance of recycled aggregate pervious concrete (RAPC) limits its application. Granulated blast furnace slag (GBFS) and copper (CS) were used as mineral admixtures to replace cement in RAPC for improving the resistance. At 10% GBFS replacement level, 5% 25% CS was added respectively, which reduced consumption cement. effects on paste fluidity, porosity, permeability, compre...
