The effect of various slag constituents on the distribution of phosphorus between slag and metal
… thesis was to determine the effects of various slag constituents on the distribution of phosphorus between slag and copper metal. The various slags and copper were reacted for six hours at 1550°C (2822°F) in a molybdenum boat, and then the amount of phosphorus in each was determined. …

Evaluating shrinkage of fly ash - slag geopolymers
… geopolymer made with Class F fly ash, slag, potassium silicate, and potassium hydroxide. Slag used was constant at 5% of the total mass of the mix. The SiO2 to Al2O3 ratio was kept constant at 3.6, the K2O to SiO2 ratio varied between 0.9 - 2.4 for molarity variations between 4 to 10, …

The skidding resistance potential of steel slag aggregates.
Steel slag, a by-product of the steel industry, has been used in road construction in South Yorkshire and the surrounding areas for the past 60 years. There is anecdotal evidence of good performance from these materials which is supported by the fact that they continue to be used today to the …

Setting and nanostructure of slag-fly ash binders
Slag fly ash binders (SFB) are room temperature hardening binders that have high strength, reasonable setting time, and lower carbon footprint when compared to ordinary Portland cement (OPC). The precursors for SFB are industrial byproducts, namely slag and fly ash. The inexpensive nature of the …

Reactivity of crystalline slag phases in cementitious systems
… Reactive industrial wastes such as blast furnace slag and fly ash have been the subject of much research and have been successfully implemented in blended cements as partial replacements for Portland cement. Other wastes, such as steel and copper slags, have been largely neglected due to their …

Electrochemically enhanced reduction of iron oxide from slag
… of iron oxide from calcia-silica-alumina slag by carbon in iron, and to determine whether the reaction rate can be increased by electrochemical means. It is shown that the reaction rate depends on both the ferric-ferrous cation ratio, and on the total amount of iron in the slag. It was …

Environmental Performance of Coal Slag and Garnet as Abrasives
… environmental performance of two abrasives, coal slag and garnet which are commonly used by shipyards and many other industries in surface preparation of metallic surfaces. Environmental performance evaluated in this study included, (1) productivity (ft2/hr), (2) consumption and or used-abrasive …

Model studies of metal-slag reactions in reaction generated foams.
… developed which simulates certain aspects of the slag-raetal-gas reactions that occur in L.3). steelmaking. In the model the molten iron was represented by a pool of sodium amalgam, the slag by a mixture of water and glycerol and the oxygen by a hydrogen chloride-nitrogen jet. Droplets of amalgam …

Performance and properties of structural concrete made with corex slag
Slag has been used in concrete as a cementitious extender for about 50 years in South Africa. Traditionally, blastfurnace slag has been used in concrete but recently a new product called Ground Granulated Corex Slag (GGCS) has become available on the market in the Western Cape Province. The …
