Stabilisation is a broad sense for the various methods employed and modifying the properties of a soil to improve its engineering performance and used for a variety of engineering works. In today‟s day soil stabilisation is the major problem for civil engineers, either for construction of road and also for increasing the strength or stability of soil and reduces the construction cost. In this t...

This paper will define the slag compositions required to obtain and control optimum foamy slag conditions in the Electric Furnace. In defining the optimal slags, consideration is given to the effects of scrap quality, carbon injection, slag basicity and MgO content. A computer model based on published phase-diagrams has been developed which graphically maps the chemistries for optimal foaming c...

In order to make better use of converter dust achieve effective pre-dephosphorization molten iron, the influence addition ratio dedusting ash and oxide scale on dephosphorization iron was compared, so as reveal reasons for decrease rate caused by dust. Through theoretical analysis, XRD, SEM-EDS, Raman infrared spectroscopy, mineral phase structure, polymerization degree phosphorus structure fin...

As the fourth-largest industry waste residue, after iron slag, steel and red mud, in China, comprehensive utilization of nickel slag is imminent. Coal-based reduction combined with magnetic separation was considered an efficient method to extract from slag. During coal-based Jinchuan ferronickel growth characteristics kinetics metallic were investigated this paper. The metallisation rate metal ...

Nickel slag is a kind of solid waste with high yield and low utilization rate. However, there large amount Fe in nickel slag, which mainly exists the form fayalite. In this study, used as raw material. The addition CaO can destroy network structure fayalite, iron-rich phase be oxidized to magnetite under oxidation condition. It beneficial recovery iron resources. effect basicity on structural r...

This paper aims at bringing a literature review on the uses and properties of popular industrial and mineral byproduct slag. At the present, most industrial slags are being used without taking full advantage of their properties or disposed rather than used. The use of slag in replacing Portland cement by GGBFS is not very common. The traditional way to utilize metallurgical slags in cementing m...

in this study, slag penetration into a magnesia refractory monolithic was investigated by the crucible test method. a synthetic calcium aluminate slag system has been used to study commercial magnesia mix refractory for 1, 2, 3, 4, 5 and 6 hours at 1450°c and 1600°c. it has been shown that the penetration rate is controlled by a diffusion mechanism at 1450°c. in this case, capillaries are the ...

The orientation of steel fibers in magnetically driven concrete and magnetically driven mortar was experimentally studied in this paper using a magnetic method. In the magnetically driven concrete, a steel slag was used to replace the coarse aggregate. In the magnetically driven mortar, steel slag and iron sand were used to replace the fine aggregate. A device was established to provide the mag...
