1. Definition

Crushed stone refers to rock fragments that have been mechanically broken down into small pieces of specific sizes. These fragments are typically produced by crushing larger rocks, such as granite, limestone, or basalt, in a quarry. The resulting material is then sorted and graded by size for various uses. Crushed stone is a crucial raw material in construction and infrastructure projects due to its durability and versatility.

2. Applications

Crushed stone has a wide range of applications across multiple industries:

• Construction:
  Used as a base material for roads, highways, and railways, ensuring stability and durability.
• Concrete Production:
  Incorporated as an aggregate in concrete, providing strength and rigidity.
• Landscaping:
  Commonly used for decorative purposes, pathways, and drainage systems in gardens and outdoor spaces.
• Erosion Control:
  Helps prevent soil erosion along riverbanks, coastlines, and slopes by acting as a protective layer.
• Industrial Use:
  Found in chemical applications and as filler material in certain manufacturing processes.

3. Types of Crushed Stone

Crushed stone is classified based on the size of the fragments and the type of rock used:

• Granite Crushed Stone:
  Known for its durability and resistance to wear, suitable for heavy-duty projects such as road construction.
• Limestone Crushed Stone:
  Popular for concrete production and road base layers due to its affordability and availability.
• Basalt Crushed Stone:
  Highly durable and often used in high-stress applications like railway ballast.
• Gravel (Pea Gravel):
  Smaller-sized crushed stones used in landscaping and drainage.
• Recycled Crushed Stone:
  Made from recycled concrete or asphalt, offering an eco-friendly alternative.

Crushed stone is an indispensable material in modern construction and industrial applications, offering both strength and versatility. Its diverse types cater to various functional and aesthetic needs, making it a cornerstone of infrastructure development.
