Precast pier slabs demonstrating the use of FRP and seawater sea-sand concrete (SSC) were completed in December 2025 in Lai Chi Chong, Hong Kong. Four distinct slab types were precast and installed at the pier for comparative performance monitoring.

The kinetic theory is often used to evaluate the long-term performance of fibre-reinforced polymer (FRP) composites. However, the fundamental deterioration mechanism of the fibre-matrix interfaces, which may change significantly with temperature, has not been rigorously examined. This paper presents a study to address this deficiency of existing studies using reactive force field molecular dynamics (MD) simulations.
