The natural sand used acquired from the river bed is everlasting supply, but now the sand resources are getting depleted and exhausted. They are driven by the acute need to find a product that can match the properties of natural sand in concrete, the sand manufactured by crushing the natural rocks. The by-product (stone dust) of the crushing and screening process of coarse aggregates is a fine aggregate. Since rock sand contains more fine particles, it requires more water; hence, quality suffers resulting in low compressive strength and durability. The quality problems caused many concrete manufacturers to think for an alternative source of sand in-place of Rock sand, Thus by using GBFS as fine aggregate in replace of natural/rock sand, we may able to conserve natural resources and its use in concrete, and compressive strength results revealed that it could be as an alternative to sand.
