Study on mechanical properties and solidification mechanism of stabilized dredged materials with recycled GFRP fibre reinforced geopolymer

open access: yesCase Studies in Construction Materials, 2022
This study used fly ash-slag geopolymer to stabilize silty clayey dredged materials (DM) with recycled glass fibre reinforced plastic (GFRP) fibre. The effects of stabilizer content and fibre content on the mechanical properties of stabilized DM were ...

Numerical modelling of CFRP internally reinforced glulam beams [PDF]

open access: yesGrađevinski Materijali i Konstrukcije
Numerous studies have proven that timber structures can be effectively reinforced using fibre-reinforced polymer (FRP) composites. In this paper a nonlinear finite element model was developed to predict bending behaviour of glulam beams reinforced with ...
