Abstract

Concrete with fly ash as replacement for cement represents a promising solution for the construction industry to deal with the issues related to the global emissions of greenhouse gases. Although numerous studies were dedicated on the material properties of concrete with fly ash. There is a need to evaluate flexural behaviour of Glass Fibre Reinforced Polymer (GFRP) over conventional reinforced concrete using fly ash as partial replacement for cement in order to promote further field applications. To accomplish the above objective in the present study, mix design for M20, M40 and M60 is carried out. Cubes, cylinders and beam specimens are casted for assessing the compressive strength, split tensile strength and flexural behaviour of concrete respectively. The use of 30% of fly ash as replacement for cement in concrete improves the workability but slightly reduce the compressive strength, split tensile strength due to slow pozzolanic reaction. The use of GFRP as reinforcement in the beam specimens with 30% of fly ash as replacement for cement improves the flexural load carrying capacity. Based on the results it can be concluded that GFRP reinforced fly ash concrete is more ductile and it has more ductility index than steel reinforced fly ash concrete and also reduces the cracks and crack width.
