Concrete is the most widely used construction material.  It is estimated that the present use of concrete in the world is approximately 11 billion metric tons every year.  TEC Service’s laboratory tests every component in the concrete mix design (cement, fly ash, slag, admixtures, fine and course aggregate) as well as the concrete mix itself.  TEC Services can also evaluate the plastic properties of the mix as well as the hardened properties.  Our laboratory performs tests that few laboratories are accredited for and proficient in performing.

TEC Services laboratory is approved and/or inspected by AMRL (AASHTO Materials Reference Laboratory), CCRL (Cement and Concrete Reference Laboratory) and the US Army Corps of Engineers for concrete testing.  Our laboratory accreditations include: ISO 17025, AASHTO R18 and we are an approved laboratory for the US Army Corps of Engineers.  Stringent quality assurance and quality control procedures provide results engineers can rely on as they consider recommendations for your project.  Our concrete laboratory has provided mix designs for the pavement industry, nuclear industry, and commercial industry.

TEC Services’ employees are active members in ACI, ASTM, ICRI, FRCA, ASCE and SWRI.  Several TEC employees are current or past committee members, committee chairs, board members and presidents of the above mentioned organizations local and national chapters.  TEC Services works closely with ASTM in the development of concrete test methods, testing guidelines and specifications.

Some of the services our laboratory provides are mentioned below:  If you have any questions about testing not listed below please feel free to call us at your convenience.
