Aggregates Over 20mm

Aggregates over 20mm refer to a type of coarse aggregate that has a nominal size greater than 20 millimeters. These aggregates are commonly used in construction projects, such as:

Physical Properties

1. Nominal Size: >20 mm
2. Specific Gravity: 2.6-2.8
3. Bulk Density: 1600-1700 kg/m³
4. Water Absorption: 0.5-1.5%
5. Crushing Value: 20-25%

Uses

1. Road Construction: Aggregates over 20mm are used as base course material in road construction.
2. Bridge Construction: These aggregates are used in bridge construction, including foundations, piers, and abutments.
3. Building Foundations: Aggregates over 20mm are used as foundation material in building construction.
4. Drainage: These aggregates are used in drainage applications, such as drainage pipes and culverts.
