ACI Spring 2016 – Milwaukee: The Concrete Convention and Exposition: Nanoscale Fiber-Reinforced Concrete


DSC_0118HBK Employee, Joshua Hoheneder presented at the American Concrete Institute’s (ACI) Spring 2016 Concrete Convention and Exposition in Milwaukee, Wisconsin.  The event was held from Sunday, April 17th, 2016 to Wednesday, April 20th, 2016 at Milwaukee’s Wisconsin Center. Joshua’s presentation, titled “Smart Materials and Sensors Based on Fiber-Reinforced Concrete”, was observed by over one hundred students, researchers, and engineering professionals on Monday, April 18th, 2016.  The presentation included results from the research he performed for his master’s thesis titled, “Smart Carbon Nanotube/fiber and Pva Fiber-Reinforced Composites for Stress Sensing and Chloride Ion Detection, while attending the University of Wisconsin – Milwaukee. Joshua’s research was performed under the guidance and leadership of Dr. Konstantin Sobolev.   The goal of the research was to observe changes in electrical conductivity in concrete structures due to crack formation or chloride ingress to monitor, in real time, the condition of critical infrastructure.  Knowing that atmospheric air is electrically insulating and chlorides, found in road salt, is electrically conductive, the project hypothesized that monitoring changes in the system would allow for the structure’s condition to be monitored and detect these deficiencies as they occur.  This system, once implemented, would allow for real-time, nonbiased, and nondestructive health monitoring of critical infrastructure.
