Constituents of Course Recycled Aggregates

Site Test
Ensure the quality and compliance of recycled aggregates with our constituents analysis, supporting sustainable and reliable construction practices.
Earthworks

Plasticity Index

Lab Test
Site Test
A higher Plasticity Index indicates a greater range of water content where soil remains plastic, signifying higher compressibility and potential for settlement.
Earthworks

Water Content

Lab Test
The Water Content Test measures the water content in soil to ensure proper compaction and stability for earthworks and construction projects.
Earthworks

Air Content

At Amtest UK, we provide expert air content testing to ensure the performance and durability of air-entrained concrete. This critical test evaluates the volume of air voids within fresh concrete, a key factor for achieving freeze-thaw resistance and enhanced workability.

What is Air Content Testing?

Air content testing, conducted in accordance with BS EN 12350-7, measures the air content in fresh concrete. Air-entrained concrete is specifically designed with controlled air voids to improve durability under challenging environmental conditions, such as frost and de-icing salts. Ensuring the correct air content is crucial for meeting project specifications and achieving long-term structural integrity.

Applications of Air Content Testing

  • Freeze-Thaw Durability: Ensures concrete can withstand cycles of freezing and thawing, critical for outdoor and exposed structures.
  • Optimised Mix Design: Verifies that the air-entraining agent is performing as expected, achieving the desired workability and strength balance.
  • Compliance: Confirms that the concrete mix complies with project specifications and regulatory standards.
