Pot and field experiments were conducted to evaluate bioavailability of Cu in contaminated paddy soil (PS) and phytoremediation potential by Elsholtzia splendens as affected by soil amendments. The results from pot experiment showed that organic manure (M) applied to the PS not only remarkably raised the H2O exchangeable Cu, which were mainly due to the increased exchangeable and organic fracti...

Using wastes as starting raw materials is a common method to reduce the production costs and the environmental pollution problems arising from such wastes. In this study the production and crystallization behavior of an iron rich glass prepared by iron and steel making wastes has been investigated. The raw materials used, were the blast furnace slag, the blast furnace dust, converter slag and s...

is known that metal which is produced by the method of electroslag remelting (ESR) has service properties superior to those of metal made by open refining and casting. This can be attributed to the better conditions which exist for refining in the specially chosen slag and for the crystallization of the metal in the case of ESR. However, the need for a two-stage metallurgical conversion (essent...

In order to investigate the influence of SiC on composition and structure mixed slag (blast-furnace slag: steel = 1:9), chemical composition, equilibrium-phase microscopic morphological characteristics elemental distribution in region SiC-reagent-tempered samples were analyzed by X-ray diffractometer (XRD), FactSage7.1 thermodynamic analysis software, scanning electron microscope, energy spectr...

The problem of the accumulation waste from metallurgical industry in Ukraine, particular, blast furnace slag, has an economic and environmental component. Therefore, main problems, first all, include absence a criterion for greening industrial sector among priorities Ukraine's policy. article examines situation slag summarizes existing experience using slags as technogenic raw materials. proble...

Blast furnace (BF) is the most used equipment for production of iron in world. It charged mainly with metallurgical coke and ferrous materials. When descending inside BF, iron-bearing materials start reducing melting other burden This leads to formation so-called primary slags from which final slag formed as descend furnace. Each charge material has a unique effect on total composition BF slag....

This research was conducted in order to evaluate fatigue behavior of asphalt mixes containing Electric Arc Furnace (EAF) steel slag. After initial evaluation of the properties of EAF steel slag using X-ray Diffraction (XRD) and Scanning Electric Microscope (SEM), six sets of laboratory mixtures were prepared. Each set were treated replacing various portions of limestone aggregates of the mix wi...

This paper analyzes how feasible it is to use electric arc furnace slag as coarse aggregate, and blast furnace dust as fine aggregate in the manufacture of hot asphalt concrete for roads. Three mixtures were designed using the Ramcodes methodology, the M1 mixture of control with conventional materials, the M2 mixture replacing 50% and the M3 mixture replacing 100% of the conventional aggregates...
