Abstract

"This project is a continuation of research done by Natalia Carey and John Myers. The first part of Natalia's research was to develop and characterize an e-glass discrete fiber-reinforced polyurea (DFRP) system for infrastructure applications. She then recommended two polyurea systems (A and B) be further examined. These polyurea systems were then applied to plain reinforced concrete and steel fiber reinforced concrete panels (SFRC). Carey found that the SFRC panels sustained less overall damage. For this project SFRC was used as the base layer in combination with the DFRP systems. In addition to the DFRP and SFRC a high-volume fly ash-wood fiber (FA-WF) material was added to act as a sacrificial layer on the panels. The FA-WF is a material that has been under development at Missouri University of Science and Technology (Missouri S&T). these panels were then tested with explosives at the Missouri S&T Mine. The panels were compared visually and analytically. The visual observations were used to compare dramatic differences in the panels, while more analytical means, like residual deflections and estimated mass loss allows panels with very similar damage to be compared. After comparing the results significantly less damage was observed in the hybrid panels that contained a foam-gap and a DFRP layer. results from this study will be used to evaluate alternative construction methods and coating systems to protect at-risk structures and their inhabitants"--Abstract, page iii.
