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.

Innovative development and structural behavior of hollow columns using inflatable molds
Structural Concrete, EarlyView.Abstract This study introduces a novel approach for constructing hollow columns using precast (PC) methods enhanced by inflatable air tubes as internal molds. The proposed method addresses practical challenges in conventional hollow column construction, such as limited constructability, high production cost, and interference between internal molds and ...

An attempt at optimizing the flow characteristics of blast furnace slag by Investigation with slag obtained from blast furnace of Rourkela steel plant, SAIL [PDF]
, 2010 Due to the softening-melting of the burden in the cohesive zone of the blast furnace, the ore layer becomes compacted and the gas passes predominantly through the sandwiched coke layer known as coke slits. For improved productivity and reduced coke rate,

Archaeometry, Volume 68, Issue 1, Page 120-131, February 2026.ABSTRACT With this contribution, an attempt is being made to chart the timeline of the invention of the European hard‐paste porcelain based on historical documents. They were evaluated to trace the development lines from Tschirnhaus's early experiments with burning mirrors and lenses in the 1680s to finding ‘wax porcelain’ around 1694 to the ...
