There was an increase in the compressive strength of concrete with GRP application and the optimum compressive strength (180 days) was 45.75 N/mm2
The bending strength in terms of modules of rupture (MOR) of 8 mm and 12 mm thick architectural panels is 8.8 N/mm2 and 16.5 N/mm2 respectively.
CaO, Al2O3 and SiO2 and other polymeric compounds in GRP waste have the potential to act as additives to improve the
binding and adhesion of concrete.
The glass fibre content improved reinforcement in the cement composites.
