 — The new grinding facility is a state-of-the-art Granulated Blast Furnace Slag (GBFS) import, grinding, and road dispatch facility that satisfies Australia's stringent energy, emissions, and site discharge regulations. The facility combines leading specialised equipment from around the world. SCL's goal was to choose the best equipment on ...

 — On Nov. 30, EGLE approved an air permit for Edwin C. Levy Co., a Dearborn company which plans to build plant at 8941 West Jefferson Avenue in Detroit which would grind up blast furnace slag from ...

As a by-product of existing industrial processes, GGBS has 10 times less embodied C02 than the average CEM1 product and can be used to replace up to 70% CEM1 in concrete*. Our products conform to BS EN 15167-1, the British standard for using Ground Granulated Blast furnace Slag in concrete, mortar, and grout.

 — The use of electric furnace ferronickel slag (FNS) as a supplementary cementitious material is the current focus of research. This study investigates the effect of mechanical grinding and chemical additives on the activity excition of FNS, as well as the associated synergistic mechanisms. This study shows that the addition of …

 — In this study, the super-fine ground granulated blast furnace slag was obtained by wet grinding (i.e. WGBBS), and an attempt to activate the super-fine ground granulated blast furnace slag by sodium sulfate (SS) and sodium carbonate (SC) was made. SS/SC-activated WGGBS samples were prepared and cured at the room …

 — Investigations were carried out on the suitability of granulated blast furnace slag as a mold material for either full or partial replacement of existing silica sand in the foundry industry.
