Synthesis and characterization of ground glass fiber reinforced polyurethane-based polymer concrete as a cementitious runway repair material

摘要

This work investigates the fabrication and improvement of the polyurethane (PU)-based polymer concrete (PC) for rapid cementitious runway repair. To overcome the low strength and moduli typically exhibited by the PU binders, the ground glass fiber (GGF) particles were employed to enhance the final mechanical parameters of the PU-based PC. A series of laboratory characterization and mechanical tests were conducted to analyze the structure and properties of the PU/GGF composites and the PU-based PC. The experimental results ascertain the enhancing mechanism of GGF particles, and a suitable GGF content is obtained. The present work reveals that the GGF particles can be a reinforcing filler for the PU-based PC. (C) 2019 Published by Elsevier Ltd.
