Crusher dust is a mix of small crushed blue metal and fines. This mix of small rock and fines means that when compacted, it binds together well and creates a strong, stable surface to work on. To make your compacted crusher dust even more stable you can compact with a …
The Quarry dust may be used in the place of river sand fully or partly. A comparatively good strength is expected when sand is replaced partially or fully with or without concrete admixtures. It is proposed to study the possibility of replacing sand with locally available crusher waste without sacing the strength
