STEEL-SLAG AS SUBSTITUTE TO NATURAL AGGREGATES, PROPERTIES AND THE INTERFACIAL TRANSITION ZONE [PDF]
, 2009 Steel-slag is a residual product of the steel industry that has potential ability to pollute the ground water and soil containing heavy metals. To overcome this problem, attempts have been made for using the slag as substitute for both coarse and fine ...

Metals, 2023 The increased utilization of pellets in blast furnaces is one of the directions for low-carbon ironmaking. As a result, the low slag rate may affect the desulfurization of the hot metal and the removal of alkali in the blast furnace. Effective desulfurization and the removal of alkali in the low slag ironmaking process have become the focus of the ...

Effects of Basic Slag, Aggregate Size and Groundwater Treatments on the Production of Chilli in Acid Sulfate Soils in a Simulation Study [PDF]
, 2008 A simulation study was conducted to evaluate the effects of basic slag (BS10 and BS20: basic slag 10 and 20 t ha-1), aggregate size (A20 and A30: aggregate sizes of soil, less than 20 and 20-30 mm) and groundwater depth (Gw0: no influence of groundwater ...

Development of Slag Management System
, 2016 Degradation of refractory liners is one of the key factors limiting the service life of entrained flow slagging gasifiers, which is caused primarily by refractory/slag interactions. Slag originates from impurities in the carbon feedstock, typically coal and/or petcoke, which melt and coalesce during gasification, flowing over the refractory liner in ...

Solubility of Chlorine in Aluminosilicate Slag Systems.
ISIJ International, 2000 Thermodynamic properties of chlorine in the CaO–SiO2–Al2O3, Na2O–SiO2–Al2O3and CaO–SiO2–Al2O3–Na2O slags have been investigated in the present study. The experiments were carried out using gas-slag equilibrium, controlling both PO2 and PCl2simultaneously (PO2=10-16 - 10-19atm, PCl2 = 10-10 - 10-13 atm at 1673–1748 K), and the solubility of chlorine in ...

Effect of P2O5 incorporated in slag on the hydration characteristics of cement-slag system
Construction and Building Materials, 2023 This paper presents the influence of P2O5 incorporated in slag on the hydration characteristics of cement-slag system. It was found that the gradual addition of phosphorus oxide in slag did not change overall mineralogy of the hydration products.
