Slag sand available (blast furnace slag)
details and specifications given below
slag sand: a non-metallic product, consisting of glass containing silicates and alumino silicates of lime, is a byproduct of metal smelting processes, produced under controlled conditions. It does not contain any materials that may affect the strength and durability of concrete, such as chlorides, organic matter, clay, silt and shells.
Granulated slag is obtained by rapidly chilling (quenching) the molten slag from the furnace by means of water or steam and air.
