This paper presents the fatigue strength and deformation behavior of particular fly ash-based geopolymer concrete (GP) obtained from uniaxial compressive fatigue tests with four load conditions. The number of cycle at failure of all geopolymer specimens was much shorter than that of the concrete made of the ordinary portland cement (OPC) shown in literatures. The fatigue strength for 2 million cycles of GP was lower than that of ordinary cement concrete in water and of light weight concrete. The residual axial strains and the lateral strains under cyclic load were larger than OPC when they failed.
