2. Ground granulated blast-furnace slag - Wikipedia

   en.wikipedia.org/wiki/Ground_granulated_blast...

   Samples of "ground granulated blast furnace slag" (left) and "granulated blast furnace slag" (right) Ground granulated blast-furnace slag (GGBS or GGBFS) is obtained by quenching molten iron slag (a by-product of iron and steel-making) from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder.

3. Energetically modified cement - Wikipedia

   en.wikipedia.org/wiki/Energetically_modified_cement

   An EMC made from volcanic rocks (Luleå, Sweden, 2020). Energetically modified cements (EMCs) are a class of cements made from pozzolans (e.g. fly ash, volcanic ash, pozzolana), silica sand, blast furnace slag, or Portland cement (or blends of these ingredients). [1]

4. Blast furnace - Wikipedia

   en.wikipedia.org/wiki/Blast_furnace

   Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide. The blast furnace operates as a countercurrent exchange process whereas a bloomery does not.

5. Slag - Wikipedia

   en.wikipedia.org/wiki/Slag

   Today, ground granulated blast furnace slags are used in combination with Portland cement to create "slag cement". Granulated blast furnace slags react with portlandite (Ca(OH) 2), which is formed during cement hydration, via the pozzolanic reaction to produce cementitious properties that primarily contribute to the later strength gain of ...

6. Cement - Wikipedia

   en.wikipedia.org/wiki/Cement

   Portland blast-furnace slag cement, or blast furnace cement (ASTM C595 and EN 197-1 nomenclature respectively), contains up to 95% ground granulated blast furnace slag, with the rest Portland clinker and a little gypsum. All compositions produce high ultimate strength, but as slag content is increased, early strength is reduced, while sulfate ...

7. Portland cement - Wikipedia

   en.wikipedia.org/wiki/Portland_cement

   Portland cement, blast furnace slag or fly ash and pozzolana * Constituents that are permitted in portland-composite cements are artificial pozzolans (blast furnace slag (in fact a latent hydraulic binder), silica fume, and fly ashes), or natural pozzolans (siliceous or siliceous aluminous materials such as volcanic ash glasses, calcined clays ...

9. Construction aggregate - Wikipedia

   en.wikipedia.org/wiki/Construction_aggregate

   Recycled material such as blast furnace and steel furnace slag can be used as aggregate or partly substitute for portland cement. Blast furnace and steel slag is either air-cooled or water-cooled. Air-cooled slag can be used as aggregate. Water-cooled slag produces sand-sized glass-like particles (granulated).
