→GB/T 50081 concrete axial tensile strength testing machine is used to perform tensile ring tensile test, embedded bolt rod tensile test, core specimen tensile test to determine ultimate tensile value and tensile modulus.
→The size of the middle section of the axial concrete specimens molded is 100x100mm, and the drill core specimens is cylinder with diameter 100mm with 4 pieces for each group.
→Tensile space is greater than 1000mm, complete the concrete pull ring tensile test, embedded bolt pull rod tensile test, clamping tensile test, drill core specimen pull plate tensile test.The microdeformation was measured with a 0.001mm micrometer.Draw the axial tensile stress-strain curve of concrete.
→After test, it can get tensile stress-strain curve.
