Abstract


  • The use of fibre reinforced polymer (FRP) and polyvinyl chloride (PVC) as strengthening materials for

    piles was found to be a promising scheme, due to their high strength-to-weight ratio, high durability

    and high anti-corrosion ability. This study presents an experimental investigation of a new form of composite

    piles: geogrid-confined pervious geopolymer concrete piles (GPGCPs) with fibre reinforced polymer

    (FRP)-polyvinyl chloride (PVC)-confined concrete core (FPCC). The GPGCP with FPCC consists of a

    circular geogrid outer tube, a FRP-PVC-confined normal geopolymer concrete core, and pervious geopolymer

    concrete (PGC) filled in between. The reason for applying PGC into piles is to increase the rate of consolidation.

    The aim of using FPCC is to improve the compressive strength and ductility of the concrete. In

    this study, two groups of GPGCPs (without and with FPCC) were prepared and tested under axial compression.

    In each group, one layer, two layers, and three layers of geogrid were used to investigate the

    influence of the outer tube. The test results show that the FPCC can significantly improve the mechanical

    behaviour of the GPGCPs. In comparison with GPGCPs without FPCC, the maximum axial loads of GPGCPs

    with FPCC were higher, and the ductility was improved significantly.
