As a result, it is also used as a concrete aggregate in the same way as natural aggregate. Granulated blast furnace slag Just like air-cooled blast furnace slag, this slag has a hydraulic property and there is no risk of alkali-aggregate reaction. Because of the powerful latent hydraulic property that results from fine grinding, this slag is used in products such as Portland blast furnace slag ...

Use fly ash, natural pozzolans, granulated blast-furnace slag, or silica fume as a cement replacement. They make the concrete mix less permeable therefore making it more difficult for water to reach the aggregate. However, before specifying them for a project mixture, test their effectiveness using ASTM C 311, C 595, C 989, C 1157, C 1260, or C 441 (Farny and Kosmatka, 1997). If Class C flyash ...

Approval and use of aggregates is based upon meeting physical test requirements in the following physical tests. Absorption The absorption quality requirement applies only to coarse aggregates, but this data is necessary on fine aggregate for other purposes, such as mix design and water/cementitious ratios. All aggregates are porous, but some are more porous than others. How porous an ...

The use of iron blast-furnace slag as a concrete, either as an aggregate or as a cementitious material, or both, is well known. The use of ground granulated blast-furnace (GGBF) slag in the production of blended cements began in 1905 in the United States. Recent attention has been given to the use of GGBF slag as a separate cementitious constituent of concrete. This report primarily addresses ...
