SDSM& T PROFESSOR ADDRESSES CONCRETE CONFERENCE IN AUSTRALIA
Dr. M. R. Hansen, SDSM& T Associate Professor of Civil Engineering, recently presented two papers at the International Conference on High Performance High Strength Concrete ( HPHSC) held at the Curtin University of Technology, Perth, Western Australia. Approximately 100 engineers and scientists from around the world attended the conference.
The papers presented by Dr. Hansen summarized the results of recent research at SDSM& T. The first paper, “ Field Performance of Concrete Admixtures,” was based on research work sponsored by the South Dakota Department of Transportation. The proper use of chemical and mineral admixtures makes high performance concrete ( HPC) possible. “ The use of high performance concrete in South Dakota has enormous potential to provide stronger and more durable concrete, thus saving the taxpayers many millions of dollars, ” stated Dr. Hansen.
The second paper, “ Using Recycled Glass as Aggregate in Concrete,” was based on research work sponsored by the Material Recovery Facility ( MRF) in Rapid City. The MRF currently extracts steel, aluminum, plastic and glass from the municipal waste stream. The MRF can sell most of the material but previously had no market for the recycled glass. “ This project has shown that the glass can be used in concrete as an aggregate replacement,” said Dr. Hansen. “ This could have far- reaching significance and world- wide benefit from an environmental and energy conservation point of view.”
Co- authors for both papers were Brenda Flottmeyer ( MS CE ‘ 98) and Michelle Nielsen ( MS CE ‘ 98). The refereed papers were published in a 739- page book that will be available in the SDSM& T Devereaux Library. Other papers include topics such as development of HPHSC mixtures, behavior and design of HPHSC structural members, field applications of high performance concrete and repair and rehabilitation using HPHSC.
