Sludge

Crusher sludge, also known as crusher fines or quarry dust, is a by-product of the crushing process in quarries and mining operations.

Properties:

1. Fine particle size (0-5 mm)

2. High silica content (60-80%)

3. Low silt and clay content (<5%)

4. Moisture content: 5-10%

5. Specific gravity: 2.5-2.7

6. Bulk density: 1.5-1.8 t/m³

Applications:

1. Construction (fill material, sub-base)

2. Road construction (base course, sub-base)

3. Landscaping (pathways, garden beds)

4. Building materials (cement, concrete)

5. Waterproofing and coating

Advantages:

1. Cost-effective filler material

2. Improves soil stability

3. Reduces soil erosion

4. Environmentally friendly (reduces waste)

5. Suitable for compacted filling
