Concrete and Aggregate Testing

Concrete and aggregate testing from SGS – helps you ensure that the quality of your concrete and aggregate complies with compulsory regulations and quality control standards.

Concrete and aggregate used in your construction projects has to meet strict regulations and quality standards. As these standards are often compulsory, concrete and aggregate testing by an independent third-party is necessary to help assure compliance. Our full range of independent concrete and aggregate testing services can help ensure both the quality of your concrete and the quality of your aggregate.

Why use concrete and aggregate testing from SGS?

As an independent third-party, we provide you with highly specialized personnel, technology and testing laboratories, along with accreditation for a wide range of national and international standards. We can help you:

  • Comply with the relevant regulations and quality standards 
  • Make informed decisions with advice, guidance and review of test data 
  • Get the testing you need with bespoke test procedures when standard testing does not suit 
  • Ensure the quality of concrete
  • Ensure the quality of aggregate
  • Evaluate the performance of available materials 
  • Control concrete quality during – and after – construction

Comprehensive concrete testing for your project

We offer you comprehensive concrete testing at every stage of your project. From on-site slump testing as you pour your concrete, through to testing hardened samples for physical characteristics in our laboratories, our concrete testing includes:

  • Sampling of fresh concrete and slump testing on site
  • Making and curing test specimens on your site and in our laboratory
  • Compression and flexural testing
  • Compression tests on molded specimens and on hardened concrete cores
  • Mass per unit volume testing for hardened concrete
  • Securing and testing cores from hardened concrete
  • Flexural strength and toughness of hardened concrete  
  • Testing for the compressive strength per unit mass of grout 
  • Water absorption and permeable voids testing
  • Apparent volume testing

A full range of aggregate testing at every stage of your project

We offer you broad aggregate testing at every phase of your project. From our on-site quality control monitoring when you source the aggregate, right through to physical characterization in our specialized laboratories, our services include testing for:

  • Bulk density 
  • Polished aggregate friction value
  • Particle density and water absorption 
  • Sieve analysis
  • Material finer than 75 ìm\
  • Particle shape 
  • Flakiness index 
  • Angularity number 
  • Fine particle size distribution 
  • Aggregate crushing value 
  • Wet/dry strength variation 
  • Los Angeles Value 
  • Soundness 
  • Weak particles 
  • Clay and fine silt 
  • Organic impurities other than sugar
  • Resistance to stripping
  • Color of aggregate
  • Average least dimension 
  • Resistance to wear by attrition 
  • Unconfined compressive strength
  • Chloride sulfate sugar content
  • Petrographic examination
  • Oversize particle size distribution and shape

Our in-house aggregate testing methods include:

  • Sampling from a conveyor belt
  • Truck, stockpile, rock spall, boulder and drill core
  • Sample preparation – stabilized pavement material
