Use of stone powder in concrete and mortar as an alternative of sand
Stone powder produced from stone crushing zones appears as a problem for effective disposal. Sand is a common fine aggregate used in construction work as a fine aggregate. In this study, the main concern is to find an alternative of sand. Substitution of normal sand by stone powder will serve both solid waste minimization and waste recovery.

Stone Dust: What It Is, Uses, and Where to Buy It
When stones are run through a crushing machine to make crushed stone, stone dust also forms. Its exact composition will depend on what kind of stone ran through the machine, such as granite or limestone. The machine has a screen that traps the larger crushed stone and lets the smaller material (or "screenings") fall through the screen.
