The invention relates to a uniaxial tensile test system for a cement-based building material, and belongs to the technical field of uniaxial tensile test of building materials. The uniaxial tensile test system for the cement-based building material comprises a test piece shape optimization module, a matched clamp optimization module for clamping a test piece, and a non-contact test module for performing a tensile test on the test piece. By optimizing the size and the shape of the test piece, the centering problem of a tension action line and the axis of the test piece is solved, the matched clamp optimization module is provided, the situation that the test piece is broken in advance due to overlarge local stress at the contact position of the test piece and the clamp is avoided, and the precision and the reliability of a test result can be ensured. And the non-contact test module is adopted, so that the technical problem that strain of an area after a critical state is difficult to completely capture, especia
