Aggregate testing is a critical component of the construction industry, involving a series of tests conducted on aggregate materials—granular components like sand and gravel—which are combined with a binder such as cement or bituminous materials to form concrete or asphalt.

The primary reason for aggregate testing is to determine the physical and mechanical characteristics of the aggregate used in construction. These characteristics include size, shape, density, strength, durability, and resistance to environmental conditions. These factors are crucial in determining the quality of the aggregate, its suitability for various applications, and its impact on the properties of the resulting concrete or asphalt mix.

The benefits of aggregate testing are manifold. Firstly, it ensures that the aggregate used in a construction project is of the appropriate quality and meets the necessary specifications. This quality assurance leads to safer and more durable constructions. Secondly, aggregate testing helps optimize the design of concrete and asphalt mixes, which can enhance the performance and longevity of structures. Thirdly, it contributes to cost savings by reducing the likelihood of failures or costly repairs due to substandard aggregate quality.

Aggregate testing should be performed before the materials are used in production. By conducting preliminary tests, potential issues can be anticipated and addressed during the production process.

Below is a list of the most common cement tests that we conduct for our clients. All our tests are performed in accordance with European Standards or ASTM:

  1. Sieve Analysis Test: Determines the classification or distribution of aggregate particle sizes.
  2. Crushing Strength Test: Measures the resistance of aggregates to crushing under a gradually applied compressive load.
  3. Friction Resistance Test: Assesses the strength or resistance of aggregates to friction.
  4. Abrasion Test: Evaluates the strength or resistance of aggregates to abrasion or wear.
  5. Shape Test: Determines the shape characteristics of aggregates, such as elongation, etc.
  6. Specific Gravity and Water Absorption Test: Measures the density of aggregates and their capacity for water absorption.
  7. Freeze-Thaw Cycling: Assesses the durability of aggregates against the effects of atmospheric conditions such as freezing and thawing.
  8. Bulk Density and Voids Test: Evaluates the weight per unit volume and the voids within aggregates.
