Abstract
A concrete deformation testing device mainly comprises a displacement sensor and an upper and lower locating frame. A plurality of fastening screw rods are respectively arranged on the upper locating frame and the lower locating frame, a sensor fixed ring is also arranged on the upper locating frame, a sensor is in the sensor fixed ring, and a fixed frame is arranged on the lower locating frame. The concrete deformation testing device uses the displacement sensor instead of an electric resistance strain gage to test the concrete deformation, the operation is easy and the adaptability is strong without drying the test piece surface. No resistance strain gage is consumed during the testing, thereby the testing cost is reduced.
