If we can determine how different crystalline materials in concrete react to stressors, we can work at this level to understand ways to make concrete more durable.” The strains on concrete roads, bridges, dams and other structures are many. Thermal stressors include the freezing and thawing processes that play havoc with roads. Mechanical loads include the weight of thousands of autos driving over a bridge or airplanes landing on runways. Chemical reactions also threaten the longevity of structures such as dams and bridge foundations. Many times the stones within the concrete experience a reaction to other chemicals in the environment or the concrete itself.

Engineering / Tennessee Tech University / Page 16 Donations critical for long- term success of the college If it weren’t for the support of our friends and alumni, the College of Engineering would not be the bright, vibrant, exciting place that we currently enjoy. Donations drive many of our most important student activities, including student conference participation, projects like the Mini-Baja and the Formula Car, lab equipment acquisi- tion, and construction of specialized facilities. The Denso Vehicle Engineering Complex, for example, is a facility that would not be available were it not for private support from Denso. Similarly, the furnishings in our new conference area (PH 225) were largely purchased with private support. Donations to the College of Engineering Endowment undergird our programs, and help us assure that the TTU of the future will have a firm footing for continued excellence.
