GGBFS C Gr
Ground Granulated Blast furnace Slag (GGBFS) is made by quenching molten blast furnace slag (a by product of iron and steel making) in water to produce a glassy granular product that is then dried and ground into a fine powder GGBFS. It consists mainly of calcium and aluminum silicates and has a chemical composition similar to these respective natural minerals and to hydrated Portland cement. GGBFS is typically finer than Type 1 Portland cement. It is an off-white color powder with a specific gravity of about 2.88 and is handled and dispersed like Portland cement.
- Fineness-blaine 420 (min.)
- Initial setting time 45 minutes (min.)
- le-chatelier expansion 10.00 mm (max.)
- Mortar compressive strength, 28 days 52.5 mpa
