Abstract Cement-based tubes are widely used in the municipal, industrial, energy and other fields, and the accurate determination of the mechanical properties is very important to the structural performance evaluation and quality control of the tube components. To solve the difficult technical issues for the mechanical determination of the cement-based tubes, the analytic formulas of the elastic modulus and bending strength were deduced based on the theory of material mechanics for the split ring and closed ring samples, respectively. The split ring method, closed ring method and three-point bending method were used to evaluate the elastic modulus and bending strength of the split ring, closed ring and beam pieces which were prepared by the sulphoaluminate cement mortar, respectively. The experimental results show that the elastic modulus and bending strength measured by the three methods are very close, and demonstrate the validity and correctness of the split ring method and closed ring method.

Key words： cement-based tubes elastic modulus bending strength split ring method closed ring method three-point bending method
