Kambara Reactor (KR) desulfurization slag used as slag-making material for converter smelting can promote early melting in the initial stage and improve efficiency of dephosphorization. However, its direct utilization a slagging increase sulfur content molten steel since KR contains 1~2.5% sulfur. Therefore, this research focuses on effect basicity precipitation behavior occurrence state order ...

Different ways of combining argon oxygen decarburisation slag (AOD) or electric arc furnace slag (EAF) with blast furnace slag (BFS) for achieving better phosphorus (P) removal performance in small-scale wastewater systems (SSWSs) were examined. The three types of slag were combined in varying mass ratios and with different dosing procedures in batch experiments using synthetic solution and rea...

This study investigates the utilization of slag and fly ash (FA) as alternative cementitious binder. Combination of 60% slag and 40% FA was used as new binder. In addition, for activation of slag and FA, sodium hydroxide and calcium hydroxide was used as a chemical activator by 5% weight of the binder, separately. Water to binder and sand to binder ratios was kept 0.55 and 3 in mortar preparati...

This paper attempts to illustrate the benefits of using slag models based on the thermodynamics of steelmaking reactions and the multi-dimensional modeling of phase equilibria. The use of mass balance calculations and the application of these personal computer-based slag models to the refinement of standard operating procedures can simultaneously result in shorter process times, more predictabl...

In this study, the influence of mechanically activated electric arc furnace slag (EAFS) was investigated through compressive strength tests on 50 mm mortar cubes. The objective was to convert the wasteful EAFS into a useful binding material to reduce the cement content in concrete without compromising strength and economy. Four different groups of mortar were cast which include control mortar, ...

concrete occupies unique position among the modern construction materials. Concrete is a material used in building construction, consisting of a hard, chemically inert particulate substance, known as aggregate (usually made for different types of sand and gravel), that is bond by cement and water. Now a days utilization of industrial soil waste or secondary materials has encouraged in construct...

In the first part of this paper we consider compact algebraic manifolds M with an algebraic (n − 1)-Torus action. We show that there is a T -invariant meromorphic section σ of the canonical bundle of M . Any such σ defines a divisor D. On the complement M ′ = M −D we have a trivialization of the canonical bundle and a T -action. If H(M ′,R) = 0 then results of [2] show that there is a Special L...

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 ...
