Nationally Recognized Cement/Concrete Testing Lab

Arrow

AET engineers and materials scientists have been instrumental in the analysis and interpretation of the performance of construction materials including cementitious materials, concrete mix designs and concrete durability throughout the U.S. As a leader at the American Concrete Institute, our co-founder Dick Stehly lectured in 25 countries and facilitated AET in building a reputation for testing, research and engineering that is proudly maintained today.

We offer an independent laboratory for sampling and physical testing as well as experts in environmental, geotechnical, construction materials, building forensics, petrography, pavements and nondestructive testing. You also gain access to a state-of-the-art chemistry lab for timely and accurate testing, evaluation and recommendations. AET is a leading partner for general contractors and their material suppliers as well as a consultant for design, engineering and forensics professionals.

In addition to basic construction materials tests, AET offers expertise in specialized laboratory services to suit project requirements. A sampling of our services includes but is not limited to:

• Admixture evaluations
• Alkali-silica and alkali carbonate reactivity
• Coefficient of thermal expansion testing
• Creep of concrete
• Durability testing (freeze/thaw; scaling resistance)
• Supplementary cementitious testing

AET's extensive service offerings help facilitate comprehensive testing and reporting — giving clients a better understanding of how their materials will react to geologic conditions, other materials and the elements when used in roadways, bridges, airport runways, rail, transit and various energy, commercial, industrial and government uses. We are responsive, precise and offer experience, expertise and capabilities to meet the challenges of the construction industry.
