The difference between crushed stone chips and machine-made sand and gravel aggregates

Crushed stone chips and machine-made sand and gravel aggregates are both materials used in construction, but they have some differences in terms of their production process, size, and shape.

1. **Production process**:

- **Crushed stone chips**: These are produced by crushing large rocks into smaller pieces. The process typically involves blasting, crushing, and screening.

- **Machine-made sand and gravel aggregates**: These are produced by artificial crushing and screening of rocks, gravel, and sand.

2. **Size**:

- **Crushed stone chips**: These are usually larger in size compared to machine-made sand and gravel aggregates. They are typically used for infrastructure projects like road and railway construction.

- **Machine-made sand and gravel aggregates**: These are smaller in size and are used for a wide range of construction purposes, including concrete and asphalt production.

3. **Shape**:

- **Crushed stone chips**: These have a more irregular shape, which makes them suitable for use in road bases and railway ballast.

- **Machine-made sand and gravel aggregates**: These have a more rounded shape, which makes them suitable for use in concrete and asphalt.

4. **Uses**:

- **Crushed stone chips**: These are typically used in the construction of roads, railways, and other infrastructure projects.

- **Machine-made sand and gravel aggregates**: These are used in a wide range of construction projects, including concrete and asphalt production, as well as in the construction of roads, bridges, and buildings.

In summary, the main difference between crushed stone chips and machine-made sand and gravel aggregates is in their production process, size, and shape, as well as their specific uses in construction projects.
