The mortar-rock bond interface direct shear tester complies with JTG E41-2005.

Mortar and Rock Bond Interface Direct Shear Tester is designed to test the shear strength of rock specimens by simulating the behavior of rock under shear force. It is primarily suitable for direct shear tests on rock blocks, structural surfaces (such as joint surfaces, bedding surfaces, schistosity surfaces, fracture surfaces, etc.), and the contact surface (bonding surface) between concrete (or mortar) and rock, as well as shear resistance tests on the interface between concrete and other materials or overall shear fracture strength tests.

Mortar and Rock Bond Interface Direct Shear Tester Equipment Features:

1. Computer automatic control, meaning parameters such as speed, force value, and displacement are controlled and displayed on the computer, with automatic analysis and calculation in the database.

2. Real-time recording of test curves during the test process, displayed and saved, with high-speed sampling.

3. Real-time display of current force values, peak values, test process information, and current displacement in the normal and tangential directions.

4. Equipped with overload protection; when the force value or displacement exceeds the rated range of the direct shear tester, it automatically unloads and stops the test.

5. Parameters such as the area and height of test blocks, environmental temperature, etc., for each test group can be modified or filled according to actual conditions.

6. Dual-system control, including manual control system and computer automatic control system.

7. Displacement measurement adopts diagonal measurement, with data transmitted to the computer in real time.

8. Conditions for automatic switching between normal loading and tangential loading can be selected.
