1. Overview of Sand and Aggregates Industry
1.1 Basic Concept of Sand and Aggregate
Sand and aggregates are granular materials derived from natural rocks and pebbles through processes such as crushing, screening, or natural weathering. They serve as essential raw materials in the production of concrete, asphalt, and roadbed construction.
| Classification criteria | |
|---|---|
| By source and process | Natural aggregate: river sand, sea sand, mountain sand (needs to be cleaned to remove impurities, chloride ion content must be less than 0.02% to comply with EU EN 13242 standard). |
| Manufactured aggregates: they are produced by crushing rocks, and those with a crushing value below 12% can meet the requirements for high-strength concrete, in accordance with China’s national standard GB/T 14684. | |
| By particle size specifications | Coarse aggregates: typically ranging in particle size from 0.15 to 4.75 mm, such as crushed stone and gravel, account for approximately 60% to 75% of the total volume of concrete. |
| Fine aggregates: With particle sizes ranging from 4.75 to 37.5 mm, such as river sand and manufactured sand, affect the workability and crack resistance of concrete. | |
| By application scenario | Construction sand: It must comply with ASTM C33 (United States) or GB/T 14684 (China) standards, with a crushing index of no more than 30%. |
| Sand used for asphalt applications: It must have a flat particle content of less than 12% to prevent pavement cracking and ensure structural integrity. | |
| Eco-friendly aggregates: It include recycled aggregates—with a construction waste recycling rate of ≥90%—and low-carbon aggregates produced at calcination temperatures of ≤800°C. |
Source
- Natural sources: Global sand and aggregate resources are primarily found in sedimentary rocks (such as limestone and sandstone) and metamorphic rocks (such as quartzite). The top ten resource-rich countries—including China, the United States, India, and Brazil—account for 75% of the world’s total reserves. River sand, valued for its rounded texture, is widely used in high-end construction; however, excessive extraction has caused ecological degradation. Seawater sand requires desalination treatment to prevent steel reinforcement corrosion.
- Artificial sources: These aggregates are produced by crushing mining waste rock, recycling construction debris (e.g., crushed concrete blocks), or processing industrial solid wastes such as steel slag and coal gangue.
- Extraction methods: The industry’s extraction is composed of 65% land-based open-pit mining, 25% riverbed and seabed dredging, and 10% recycling and reuse.
