Non-Water Reacted Two-Component Polymer Based on Impact Resonant Test in Oceanic Traffic Engineering

Non-water reacted two-component polymer (NRTCP), a newly invented polymeric material, has been widely used in various engineering projects because of its advantages, such as impermeability, time saving, and labor saving. Impact resonance test (IRT) is a type of nondestructive test method. This method has been applied to obtain the dynamic elastic modulus of Portland cement concrete and pavement asphalt traditionally, but it has not been used to test NRTCP. In this study, the damping ratio and elastic modulus of NRTCP are obtained through IRT under different circumstances, such as various liquid depths, salt contents, immersion times and densities. Results show that all changes remarkably affect the damping ratio and dynamic elastic modulus of NRTCP. These findings provide a reference for NRTCP usage in oceanic traffic engineering.
