Viscosities of Iron Blast Furnace Slags

ISIJ International, 2014
The viscosities of the industrial and synthetic iron blast furnace slags have been measured using a custom designed rotating bob apparatus. This advanced apparatus enables control of the gas atmosphere and rapid quenching of the samples on completion of the viscosity measurements.

Influence of an Electromagnetic Field on Direct Reduction of Iron Oxide Using Hydrogen as a Reducing Agent

steel research international, Volume 97, Issue 8, Page 4119-4125, August 2026.
This study investigates the reduction of pure iron oxides and industrial iron ore using hydrogen gas as a reducing agent. Additionally, to determine whether the reduction process can be accelerated, electromagnetic fields of 50 Hz and 25 kHz were applied.

Efficiency of Superplasticizers in Low‐carbon Alkali‐activated Slag–Silica Fume Binders Governed by Polymer Solubility

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Workability control of alkali‐activated binders (AABs) remains an obstacle to producing low‐carbon clinkerless ultra‐high‐performance concrete, as their formulation usually necessitates low water‐to‐binder (W/B) ratios, high binder content, and concentrated activator solutions. To address this challenge, a greener and more manageable composite

Expanded Blast-Furnace Slag Aggregates

Journal of the Society of Materials Science, Japan, 1966
高炉からの溶融スラグに適当量の水を接触させて, 膨張高炉スラグを作り, これより破砕ままのスラグ骨材, 粒形を改良した球状化スラグ骨材, 粒形を改良し, 表面に被覆剤をコーティングした被覆スラグ骨材の3種を製造し, それぞれについて軽量コンクリート骨材としての諸性質を試験した. その結果, 三者とも良好な性質を有しており, 特に球状化スラグ骨材, 被覆スラグ骨材の諸性質は著しく改良され, 構造用軽量コンクリート骨材として使用可能であることがわかった.膨張高炉スラグ骨材をコンクリート骨材として使用する場合, 製造コストの面で有利な, 破砕ままのスラグ骨材, 球状化スラグ骨材の両骨材について, コンクリート調合のめやすとなる調合図を作製した.
