Abstract：Carbon nanotubes reinforced cement-based concrete can give full play to their excellent properties, but the limitation of the cost of carbon nanotubes make the research and application of carbon nanotubes concrete lag behind.Therefore, the experiments of carbon nanotubes shotcrete with uniaxial compressive stressstrain curve, elastic modulus, and Poisson'ratio are researched and compared with those of the ordinary shotcrete, steel/macro-synthetic fibers shotcrete, and macro-synthetic/polypropylene fibers shotcrete.Finally, the recommended formula GB50010—2010 is determined as a stress-strain equation for carbon nanotubes concrete, and at the same time, the formula of elastic modulus and the experimental results of Poisson'ratio are obtained.The failure pattern and constitutive relations show that toughness and ductility of carbon nanotubes are superior to other groups of shotcrete.
