Abstract: In this present study an effort was made to know the fracture behavior of Geopolymer concrete beams with different molarities. The beams which were made of geopolymer concrete with notch were subjected to three point bending test and load vs. deflection curves for all the members were obtained. From the obtained data fracture properties such as fracture energy, fracture toughness and nominal stress were determined. The test showed increasing trend in fracture property such as fracture toughness, fracture energy and nominal tress in molarity range from 12M to 14M after which it showed decreasing trending in the molatity range of 14M to 16M.
