Abstract The modulus of elasticity a concrete depends on the elastic stiffness both cementitious matrix and aggregate–ITZ system, which includes any slippage mechanisms under loading between aggregate within interfacial transition zone (ITZ). A procedure is presented in this paper to estimate an system matrix, by considering relative volumes porosities components. method was validated determini...

The current trend in the development of self-compacting concrete with sustainable construction materials has served as a guide to design novel concrete, siderurgical by-products (steel slag aggregates and cupola powder supplementary cementing material) that also meets demands high-performance concrete. This research sets out clarify unknown behavior its durability, which is ability withstand an...

In developing country like India due to the remarkable development in road infrastructure, Soil stabilization has become the major issue in construction activity. Stabilization is an unavoidable for the purpose of highway and runway construction, stabilization denotes improvement in both strength and durability which are related to performance. Stabilization is a method of processing available ...

Roads are currently essential links of communication and economic development. However, these roads progressively requiring higher quality materials, implying a greater impact on the environment, in order to withstand high levels heavy vehicle traffic. Therefore, this research proposes use industrial by-products create bituminous mixtures which more resistant durable than traditional ones. The ...

The first part of the project is mainly about changing of slag compositions and see it affect on the inclusions in the ladle furnace. The second part of the project is to study the influence of stirring (EMGAS) on the large inclusions in the steel by changing stirring conditions. The project has done at Uddeholm AB, Hagfors. First, the scrap is melted in ARC furnace then moved to the ladle de-s...

Due to the rapid growth of non-linear loads, such as power electronic control equipments and Electric arc furnace (EAF) power quality problems such as harmonics and voltage flicker are introduced in the power system. It occurs because of the time-varying and nonlinear behaviour of the Load. Arc furnaces are used in industries for induction heating and welding. Hence an Electric arc furnace mode...

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 ...

Electric arc furnace baghouse dust (EAFD), a waste by-product of the steelmaking process, contains the elements that are volatilized from the charge during the melting (Cr, Pb, Zn, Cu and Cd). The results of leaching tests show that the concentration of these elements exceeds the regulatory limits. Consequently, EAFD cannot be disposed of in ordinary landfill sites without stabilization of the ...
