Aggregate Testing

Aggregate Testing for Quality, Performance & Standards Compliance

Aggregates typically make up approximately 60–80% of concrete by volume, making their quality and characteristics critical to concrete performance. SGS TEC Services provides comprehensive aggregate testing services to evaluate material properties, quality, durability, and conformance with applicable standards and specifications.

Our laboratory tests aggregates for use in concrete, mortar, construction, and infrastructure applications. Results can also provide valuable information for aggregate selection, quality control, troubleshooting, and concrete and mortar mix design.

Whether you need routine quality control testing or an in-depth forensic investigation, our laboratory can help you understand how a material is performing and why.

Evaluating Aggregate Quality & Performance

Aggregates used in concrete must meet specific requirements for grading, cleanliness, strength, durability, and other physical and chemical properties. Materials may also need to be evaluated for potentially harmful constituents or characteristics that could affect bonding, durability, or long-term concrete performance.

Our experienced laboratory team performs standardized testing to help determine whether aggregates meet applicable ASTM, AASHTO, DOT, project, and material specifications.

Clients rely on SGS TEC Services for independent aggregate testing to support material qualification, source evaluation, quality-control programs, mix design development, and investigation of performance concerns.
