Shotcrete

Definition

Shotcrete is a low-slump concrete mixture deposited by being blown from a nozzle at high speed with a stream of compressed air. It is also known as pneumatically-projected concrete.

Purpose

The purpose of shotcrete is to provide a method for placing concrete in areas where traditional pouring methods are impractical, allowing for high-strength, durable concrete applications.

Examples of Use

• Tunnel construction uses shotcrete to create strong, durable linings.
• Retaining walls and slopes are stabilized with shotcrete applications.
• Swimming pool construction employs shotcrete for creating smooth, curved surfaces.

Related Terms

• Gunite: A dry-mix version of shotcrete, where dry materials are mixed with water at the nozzle.
• Sprayed Concrete: Another term for shotcrete, emphasizing the method of application.
• Reinforcement: Steel bars or mesh embedded in shotcrete to enhance strength and durability.

Notes

Shotcrete is valued for its versatility and ability to adhere to various surfaces, making it ideal for complex structures and difficult-to-reach areas.
