The invention discloses a concrete stress-strain full-curve test apparatus and working method. A square sleeve is used as a test piece clamp to be clamped between two ends of a test piece. On one hand, a displacement sensor can be more firmly fixed on the test piece, and when the test piece is instantaneously damaged, the movement of the displacement sensor can be effectively prevented from influencing a test result; and on the other hand, the square sleeve is made of a high-strength steel material, and under the condition of transverse deformation of the test piece, the test data can be prevented from being influenced by the stress deformation. The concrete stress-strain full-curve test apparatus is simple in structure, reasonable in design, easy in operation, firm, unlikely to deform andcapable of being used circularly for a long time. When the test piece is under the stress, the test piece is greatly deformed in the transverse direction, so that an ordinary test clamp is likely todeform under the squeezing to influence the secondary use; however, the concrete stress-strain full-curve test apparatus is made of the high-strength steel plate, so that the deformation is unlikely to occur, the repeat test can be carried out, and the test result is accurate.
