This paper has influence on discovering the behavior of hybrid polypropylene fiber reinforced geopolymer concrete under constant and elevated temperature with the purpose to determine the mechanical properties of the material. While the expertise and acquaintance with concrete behavior under constant temperature are well known, the behaviour under elevated temperature has to be seriously explored. This study objectives is to match between the mechanical properties of unburnt and burnt fiber reinforced geopolymer concrete. This study uses experimental investigation. Compression and splitting tensile tests were conducted on the 150 mm cilinder mold. Meanwhile, flexural tension test was conducted on 100 mm x 100 mm x 450 mm rectangular mold. The result of both materials, without set fire to and with set fire to, are analyzed. The gained findings for burnt material are the compression test value cut down, otherwise, the splitting tensile test and flexural tensile strength grade increase.
