Abstract：
The test result of simple shear was introduced to discuss the technical principle and characteristics of simple shear test for compressive strength of concrete. Simple shear method is a new test method for concrete compressive strength, using the shear strength of concrete to deduct the compressive strength. This method drills a core of 44mm diameter and 40mm depth on the surface of concrete structure, but doesn't draw it out, and then covers a shear head equipped with chuck on the left and right sides on the core to apply a shearing force and to cut off the core at 25mm depth.
