“Green” Concrete Technologies for Sustainable Development
With worldwide population expected to increase steeply over the next few years, it is critical to produce green materials and apply intelligent design to maintain environmental and economic sustainability during infrastructure development. Concrete is the dominant material used in construction, and the concrete industry is the largest consumers of natural resources and energy. “Green” technologies have to be incorporated in the concrete industry to meet sustainable development challenges. This paper reviews these up-to-date environment-friendly technologies through “green” concrete research projects performed at the University of Colorado Denver in recent years. These projects examine three areas of need: conservation of virgin materials, improvement of concrete durability, and emerging technologies. In addition, this paper identifies barriers to incorporate these technologies and discusses how to increase “green” concrete use in construction. The information presented in this paper will help guide the concrete industry to meet the requirements of sustainable development, which balances people’s needs, economic development, and environment protection.

Ph.D. Candidate, Department of Civil Engineering, University of Colorado Denver, Denver, Colorado, USA
Andrea V. Solis is a PhD student in civil engineering at the University of Colorado at Denver. Her research currently focuses on sustainable concrete pavements with an emphasis on the application and performance of high volume fly ash concrete and pervious concrete pavements in the U.S. and India. Additionally, her research deals with a U.S. and India comparison of material flow and life cycle analysis of cement manufacturing. Andrea has a B.S. and M.S. degree in civil engineering from New Mexico State University (NMSU) and graduated as the Outstanding Senior in the School of Engineering at NMSU. Her M.S. research at NMSU focused on the behavioral evaluation of a Simple for Dead Load-Continuous for Live Load steel girder bridge, in Las Cruces, New Mexico. She is currently a member of the UC Denver Center for Sustainable Infrastructure Systems, Chi Epsilon (civil engineering honor society), American Society of Civil Engineers, American Concrete Institute, Tau Beta Pi, and Phi Kappa Phi.
