Laboratory Evaluation on Performance of Glass Fiber Reinforced Plastic Mortar Pipe Culverts

Abstract

This paper investigated the performance and behaviour of glass fiber reinforced plastic mortar (FRPM) pipes under different loading conditions. FRPM pipes with inner diameter of 1500 mm were prefabricated in factory. Mechanics performance testing (ring and axial compressive strength and elastic modulus), stiffness and fatigue test were carried out in laboratory. Ring stiffness test provided pipe stiffness (PS) which is a function of geometry and material type of pipe through parallel plate loading test (PPLT). The fatigue test and micro-structure measure method were used to evaluate the durability effects of FRPM under repeated compression load. Results indicated that FRPM pipes had better mechanic performances as the road culverts under soils. It may be helpful for the design and construction of FRPM culverts.

Effect of Grain Distribution on Resin Consumption and Mechanical Performance of GRP Pipes

“…The problem of the best possible grain distribution of aggregates and their contribution to optimum proportioning for the concrete mixture has been the issue of numerous experimental and theoretical investigations. Shi and Wei [14] examined the mechanical properties of glass fiber reinforced plastic mortar pipes with an inner diameter of 1500 mm under different loading conditions. In their study, ring and axial compressive strength and elastic modulus, stiffness and fatigue test were carried out.…”
