The increased utilization of pellets in blast furnaces is one the directions for low-carbon ironmaking. As a result, low slag rate may affect desulfurization hot metal and removal alkali furnace. Effective ironmaking process have become focus steel industry. In this paper, effects quantity, temperature, reaction time composition on were studied using slag-metal method. It was found that quantit...

To foster the practical development of the constructed wetlands used for water quality enhancement in Turkey, 2 vertical subsurface flow pilot-scale constructed wetlands were implemented on the METU campus, Ankara, Turkey. Both of the wetlands were planted with Phragmites australis and operated identically at a flowrate of 3 m3.d−1 and a hydraulic loading rate (HLR) of 0.100 m.d−1, intermittent...

During the production of concrete, cement, water, aggregate, and chemical and mineral admixtures will be used, and a large amount of carbon dioxide will be emitted. Conversely, during the decades of service life of reinforced concrete structures, carbon dioxide in the environment can ingress into concrete and chemically react with carbonatable constitutes of hardened concrete, such as calcium h...

Stabilisation/solidification (S/S) is an effective technique for reducing the leachability of contaminants in soils. Very few studies have investigated the use of ground granulated blast furnace slag (GGBS) for S/S treatment of contaminated soils, although it has been shown to be effective in ground improvement. This study sought to investigate the potential of GGBS activated by cement and lime...

The climatic change such as the global warming is one of important international problem. On field construction materials, environmental-conscious concrete which are CO2 reduction from materials advance development and practical application. Mostly these techniques use equivalent for type C blended cement that used a large amount mineral admixtures substitution cement. However, only underground...

HIsmelt is well suited for smelting vanadium–titanium magnetite due to its flexibility in feedstock selection and tolerance high viscosity slag, compared with the blast furnace. In this work, effect of time on distribution behavior recovery rates vanadium titanium was investigated by experiment first time. The relationship between slag temperature at different times further revealed thermodynam...
