Experience

Mark Haddad joined the WJE team in 2015 bringing with him more than ten years of experience in construction materials testing. While working with agencies and companies such as the Illinois Department of Transportation, Vulcan Materials and Lafarge North America, he has carried with him a vast knowledge of raw materials and evaluations. 

Mr. Haddad primarily assists departments in sample preparation along with destructive and nondestructive testing. His projects include, but are not limited, to the following:

Construction Laboratory:

Making and curing of concrete specimens, concrete compressive strength testing, aggregate preparation and testing, and absorption and saturation coefficient.

Structural Laboratory:

Flexural and transverse breaking strengths, modulus of rupture, weather resistance of slate specimens, and anchor testing.

Petrography Laboratory:

Lapping and polishing samples for microscopy evaluation and preparing thin sections.

Chemistry Laboratory:

Fineness testing and grinding specimens for chloride analysis.

 

Mr. Haddad also plays a pivotal role in the aggregate proficiency testing for the Cement and Concrete Reference Laboratory (CCRL), along with updating and maintaining the lab’s quality assurance accreditation, including ISO 17025 and AASHTO.
