UHD Concrete Research Project Earns National Award

Summary

By Mark Kramer

UHD Associate Professor Dr. Arash Rahmatian has received national recognition for his research efforts in green concrete construction.

Rahmatian’s Bio-friendly Byproduct Slag Cement Benefit to the Drainage Systems project received the Research Award at the Slag Cement Association’s (SCA) Project of the Year Awards.

According to Rahmatian, the subject of application of slag in concrete for sustainability and environmental impact was always a focus, because of the usage of products with less carbon footprint and minimal cost. Rahmatian and his student Juan Valdez collaborated on the project.

“As a result of our research, we were able create a mix design that satified special requirements for the cost and application in drainage systems, which minimize surface friction of the concrete pipes and enhanced discharging speed flow,” Program Coordinator of UHD’s Structural Analysis & Design Engineering Program said. 

With an extensive history of flooding, the research of the use of slag concrete is especially relevant to the city of Houston.

“This idea is used specifically for the cities that are highly prone to flooding,” Rahmatian said. “The high density of water accumulated in a short period of time is the concern that we considered in our design.”

In past semesters, Rahmatian's students developed possible solutions using a unique mix of lightweight and high performance concretes (HPC). UHD’s team of students are ranked among the top 10 universities nationally and have earned the “excellent university” award from the American Concrete Institute (ACI) as a result of their performance in national competitions.

“Our concrete lab has been always a hub for students who are interested in research and enhancement of their knowledge,” he said. “I have always been engaged with the concrete industry since I was in grad school and my eagerness for research provided me even more opportunities. I wanted to provide the same for our UHD students.”

To that end, many of Rahmatian’s students serve on ACI local and national committees and also are working toward certifications through some of his courses. The path of Rahmatian’s students earning their certifications was highlighted in Concrete International magazine.

“Concrete is the second most consumed substance in the world after water,” he said. “Our students can get certified and involved with internships and permanent jobs quickly in this rich industry. With the extensive interest in the construction of concrete structures, it makes this high-demand industry strong and resilient in any fluctuating economical market."

About the University of Houston-Downtown

The University of Houston-Downtown (UHD)—the second largest university in Houston—has served the educational needs of the nation’s fourth-largest city since 1974.

As one of four distinct public universities in the University of Houston System, UHD is a comprehensive four-year university led by Interim President Dr. Antonio D. Tillis. Annually, UHD educates more than 15,000 students; boasts more than 51,000 alumni and offers 44 bachelor’s, nine master’s degree programs and 16 fully online programs within five colleges (Marilyn Davies College of Business; Humanities & Social Sciences; Public Service, Sciences & Technology; and University College).

UHD has the most affordable tuition among four-year universities in Houston and one of the lowest in Texas. The University is noted nationally as a Hispanic-Serving Institution, Minority-Serving Institution and Military Friendly School. For more on the University of Houston-Downtown, visit www.uhd.edu.
