TEC Services is an AASHTO approved laboratory facility. 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.
Our laboratory service includes testing every component in the concrete mix design (cement, fly ash, slag, admixtures, find and course aggregate) as well as the concrete mix itself. TEC Services can also evaluate the flexural performance of fiber-reinforce concrete using parameter derived from the load-deflection curve obtained by testing a simply supported beam under third-point loading using a closed-loop, servo-controlled testing system.
Other services our laboratory provides are mentioned below:
CONCRETE TESTING
Compressive Strength
Absorption
Splitting Tensile
Flexural Strength
Modulus of Elasticity
ACI Mix Designs

Petrography and forensic analysis of concrete, aggregate and cementitious materials
Physical testing of construction materials, concrete, shotcrete, masonry, wood and steel.
PETROGRAPHIC SERVICES
TEC Services provides petrographic analysis of aggregate, concrete and cementitious-based products and materials to aid in failure analysis investigations and quality control testing of building materials. This analytical tool can determine the following concrete, mortar and other cementitious products characteristics:
Estimation of water-cement ratio
Cause of surface defects
General quality and condition
Depth of carbonation
Identification and volumetric estimation of pozzolanic materials
Identification of deleterious materials and reactions
Alkali-silica reactivity
Chemical and physical sulfate attack
Degree of carbonation and other environmental effects
Segregation of Materials
Aggregate quality
Maximum aggregate size and gradation
Entrapped and entrained air contents
