To study the mechanical properties of sprayed concrete at different ages,this article has conducted uniaxial compressive strength tests,splitting tensile strength tests and Young's modulus tests,and has analyzed the changes in the mechanical properties of sprayed concrete over time.The experimental results show that the early strength of sprayed concrete develops rapidly,with the uniaxial compressive strength and splitting tensile strength at 1d reaching 50%of the strength at 28d,and the Young's modulus reaching 60%of the strength at 28d.The uniaxial compressive strength is linearly related to the splitting tensile strength and Young's modulus at the test age.
