Abstract: Geo polymer concrete is one of the emerging construction material as a substitute for conventional cement concrete, eliminating the usage of OPC. This work is aimed to cast and testing of geopolymer slab elements with restrained edge condition. The size of slab panel is 1m x 1m x 0.05 m. By using yield line theory, the moment of resistance and maximum deflection under flexural loading are calculated for the of GPC slabs. Reinforcement details of these slabs are calculated using ultimate load method as per IS code provisions. As the slab element is a composite material the experimental work is carried for determination of mechanical properties GPC matrix and casting and testing of slab elements under UDL. Test results are compared with the theoretical computations for bending moment and maximum deflections. The crack pattern of slabs in experimental work is also compared with yield line patterns ( Developed for RCC).From the test results it is observed that the behaviour of GPC slabs under flexural loading is similar to conventional concrete slabs

Keywords: Geo Polymer Concrete, Slabs, Flexural Behavior, Yield Line Patterns , Load vs Deflections.
