GGBFS - Granulated Blast Furnace Slag
Granulated Blast Furnace Slag is obtained by rapidly chilling (quenching) the molten ash from the furnace with the help of water. During this process, the slag gets fragmented and transformed into amorphous granules (glass), meeting the requirement of IS 12089:1987 (manufacturing specification for granulated slag used in Portland Slag Cement). The granulated slag is ground to desired fineness for producing GGBS.
GBFS - Granulated Blast Furnace Slag
GBFS is formed when molten blast furnace slag (BFS) is rapidly quenched from the furnace, rather than left to slowly solidify by air-cooling.
On casual examination, GBFS would pass for river sand, with a top size of about 6mm. It typically has a density of about 60 – 70% of natural sand.
Fly Ash is a byproduct of coal-fired power plants that develops cementitious properties when mixed with cement and water. Fly ash in concrete is widely used across the world to strengthen concrete. It is an economical replacement for Portland cement used in concrete, while it improves strength, segregation, and the ease of pumping concrete.
