Due to various architectural requirements the structures are subjected to large shear stresses and hence the study of shear performance of structural materials is essential. Push-off test is a simple test which can be performed to determine the in-plane shear strength (IPSS) of materials effectively. Geopolymer concrete is a recent construction material which is a suitable alternative cement concretes especially in precast construction due to the non-requirement of cement, the manufacture of which is energy intensive and involves the liberation of CO
2 which is a known pollutant and leads to global warming. Concrete has good performance under compressive loads and fails generally due to crack propagation, bridging of these cracks can improve the load carrying capacity of the concrete, addition of fibre is one such method available where the fibres act as crack arrestors. The present experimental investigation has made an effort to understand the influence of fibres over shear strength of Geo Polymer Concrete (GPC) adopting push-off specimen. From the experimental studies it was observed that shear strength and resistance against cracking increased with increase in fibre volume and the effectiveness of GPC reinforced by fibres were higher than that of NSC specimen.
