The bending strength of the 12 mm thick panel with 5% GRP waste fibre was 46% higher than that of 8 mm thick panels.
Application of GRP waste fibre increased the bending strength of architectural cladding panel about 36% over control specimens.
Moreover, with the application of 5% GRP waste fibre, the bending strength of the 8 mm thick panel increased about 25% as compared to without GRP waste fibre.
Since, the quantity of cement used in this study was lower than that of the normally used cement to sand ratio (i.e. 1:0.5 to 1:1), the bending strength was found to be lower than the conventional and commercially available
products which is in concurrence with the work of Bentur and Mindess [10].
Moreover, the GRP waste fibre characterisation results from this study revealed that the GRP waste fibre sample had a wide particle size ranging from 500 micrometre to 2 mm.
Consistent quality of GRP waste fibre was expected to improve the bending strength of cement composites.
