Finding an alternative material for building constructions is an essential topic nowadays after the weather pollution which caused by cement protection factories, at the same time, the engineers thinking to find such material from environments wastes to minimize the earth pollutions. Geopolymer is very important material which satisfy such purpose, because it is minimizes the need to concrete production and overcome the environment from many slags. Geopolymer beams were casted and tested under repeated load to study the possibility of using them as structural members exposing to repeated loads.  The beams also strengthen by steel fibers and glass fiber reinforced polymer (GFRP) to investigate their effect on such new structural member. It was concluded that, it has been observed that the structural behavior of geo-polymer concrete beams tends to be more flexible when compared to that of ordinary concrete beams. Also, the geopolymer members showed an improvement in strength when using the steel fibers and GFRP, which what was observed on conventional concrete.
