Product type
20mm crushed aggregate is a type of construction material made from crushed stone, typically sourced from quarries. It consists of stones that have been mechanically crushed to a uniform size of 20 millimeters. This aggregate is commonly used in various construction applications, including concrete production, road base, and drainage systems due to its excellent load-bearing properties and drainage capabilities.
| Size | 20mm diameter |
| Material | Natural stone, typically granite, limestone, or basalt |
| Shape | Angular, promoting interlocking |
| Density | Approximately 1.5 to 1.7 tons per cubic meter |
| Moisture content | Typically less than 5% |
When choosing 20mm crushed aggregate, consider the specific application and required properties, such as density and moisture content. It's important to specify the source material, as different stones can affect performance. Additionally, inquire about any relevant certifications or compliance with local building codes, and provide estimated quantities needed for your project to receive accurate quotes.
