Microwave technique were used to investigate the early hydration of slag cement with different slag percentages, different activators and different amount of activator. It is found that higher slag cement causes a higher dielectric constant E and a shorter induction period. But higher slag cement samples have very different electrical conductivity (3 compared with that of pure cement, their o c...

One purpose of this article is to draw attention to the seminal work of J. Mealy in 1989 on calibrations in semi-riemannian geometry where split SLAG geometry was first introduced. The natural setting is provided by doing geometry with the complex numbers C replaced by the double numbers D, where i with i = −1 is replaced by τ with τ = 1. A rather surprising amount of complex geometry carries o...

Chromium pollution has been historically widespread throughout the world. Most available remediation technologies often require energy consumption. This study is aimed to develop electrochemical remediation for Cr(VI) in chromium-slag leakage with self-generated electricity. Dynamic leaching experiments of chromium-slag samples were conducted to survey the release and leaching behavior of Cr(VI...

The issue of excess slag waste generated in the iron and steel making industries has prompted investigations on use waste. objective this study is to develop an adsorbent capable capturing carbon dioxide (CO2) by using slag. A mesoporous CaO-Fe2O3-SiO2 (CFS) composite was synthesized from a dephosphorization slag, Pluronic 123 as template various acids, including formic acid (FA), hydrochloric ...

Alumina is a common substance deporting in copper smelting slags when various secondary fractions, e.g. e-scrap or WEEE, are used as feedstock such along with primary sulphide concentrates. Properties of iron-silicate at high alumina concentrations, the iron-alumina spinel saturation, have been studied 1300 °C by temperature equilibration-quenching method combined EPMA (electron probe microanal...

For beneficiation of converter slag, the role of surface phenomena on slag composition was studied. This work includes some experimental data, which were measured for basic oxygen steel (BOS) slag in Isfahan Steel Plant. All data were collected on site in the plant. The results support the idea that surface activity plays a major role in converter slag formation. It was also a new finding t...
