What kind of stone is gravel?
Gravel is one of the common materials in construction projects and is widely used in road paving, concrete production, foundation filling and other fields. However, many people do not understand the classification, characteristics and uses of gravel. This article will combine the hot topics and hot content on the Internet in the past 10 days, introduce the relevant knowledge of gravel in detail, and display its classification and application scenarios through structured data.
1. Definition and characteristics of gravel
Gravel refers to smaller rock particles formed through mechanical crushing or natural weathering. It is characterized by irregular shape, rough surface, and good compressive strength and stability. Gravel comes from a wide range of sources, including granite, limestone, basalt, etc.
2. Classification of gravel
According to different particle sizes, materials and uses, gravel can be divided into the following categories:
| Classification criteria | type | Features |
|---|---|---|
| According to particle size | Coarse gravel (20-40mm) | Commonly used for roadbed filling |
| According to particle size | Medium gravel (10-20mm) | for concrete aggregate |
| According to particle size | Fine gravel (5-10mm) | for pavement |
| by material | Granite gravel | High hardness and good wear resistance |
| by material | limestone gravel | Cheap and easy to process |
| by material | basalt gravel | High compressive strength and durability |
3. Application scenarios of gravel
Due to its unique physical properties, gravel is widely used in the following fields:
| Application areas | Specific use | Recommended gravel types |
|---|---|---|
| construction project | Concrete aggregate, foundation filling | Medium gravel, granite gravel |
| road works | Roadbed laying and pavement repair | Coarse gravel, basalt gravel |
| garden landscape | Decorative paving, drainage layer | Fine gravel, limestone gravel |
| water conservancy project | Slope protection and dam reinforcement | Coarse gravel, basalt gravel |
