The Structural Engineering and Materials Program of the Via Department of Civil and Environmental Engineering at Virginia Tech provides graduate study and research opportunities in a broad range of subject areas in structural engineering and structural materials. The objective of the program is to provide a quality education that is well-balanced in theoretical and practical considerations. There is a general emphasis on application of computer techniques and on experimental research. The research program in structural engineering and structural materials at Virginia Tech spans a number of subject areas. The laboratory also houses the necessary equipment for evaluation of the performance of concrete and asphalt. Concrete and concrete- making materials performance evaluation equipment include rapid and critical dilation freezing and thawing cabinets, a computer-driven microscopic air void analysis apparatus, corrosion rate measuring devices, state-of the-art image analysis system, petrographic microscope, and facilities for wet chemical analysis.
