Abstract Engineered cementitious composite (ECC) has excellent toughness, dissipation capacity and distribution of multiple cracking, application of ECC can improve seismic ability of structure. The compressive properties, deformation mechanism and size effect of ECC were studied based on the uniaxial compression test of 60 specimens with three different height-thickness ratio. Accor-ding to the test results, the axial compressive stress-strain curves and performance rule of different specimens were obtained.Engineered cementitious composite showed good compressive resilience in the compression failure, which was markedly different from ordinary concrete. The destruction of ECC specimens remains relatively complete and the ultimate strain was 10 times higher than concrete.Different from ordinary concrete prism test results,the ratio of height to thickness had little effect on the strength of ECC prism. However,the height-thickness ratio has a great influence on the peak strain and toughness index of ECC prism. Furthermore, the microstructure of ECC with high toughness was observed through scanning electron microscope, and fiber distribution, bridge connection situation and fiber reinforcement mechanism of ECC were analyzed.
