It is foreseen that the properties of Polymer Concrete (PC) can be further
enhanced if the PC is bonded to or sandwiched between Glass Fibre Reinforced
Plastic (GFRP) laminates, later termed as PC-GFRP system. In the present
investigation, the performance of PC-GFRP was assessed in terms of its bending
strength and bonding strength between PC and GFRP. Panels of PC size 500
mm × 500 mm × 20 mm were prepared. The panels then were cut into specimens
of appropriate geometry and dimensions required for the tests. Four (4) different
resin contents and different percentages of aggregate of different particle size
distributions were employed in preparing the PC-GFRP specimens. A batch of
PC specimens was layered with a Glass Fibre Reinforced Plastic (GFRP)
laminate on one side (SSL) and the other batch PC specimens were sandwiched
with two GFRP laminates (DSL). The PC-GFRP specimens were tested their
bending strength under three-point load test and bonding strength between
PC as a core material and glued GFRP laminate(s). The results showed that an
increase in the resin content increases the bending strength of the PC regardless
of the aggregate grading. The results also revealed that the PC specimens with
well-graded aggregate recorded the highest bending strength, with coarser
grading resulted in further increase. The bending strength of the PC-GFRP
