YZ-30C digital display rock direct shear instrument
YZ-30C rock digital display stress type direct shear instrument is developed and manufactured according to the following national industry standards:
SL264-2001: Specifications for rock tests in water conservancy and hydroelectric engineering;
JTG E41-2005: Test Method of Rock for Highway Engineering.
The instrument adopts the horizontal push method, and is mainly suitable for direct shear tests on rock blocks, structural surfaces (such as the joint surfaces, the inside of the layers,the inside of the slices, the cracking surfaces, etc.) and the contact surfaces (cemented surfaces) betwen concrete (or mortar) and rock, and the test of the shear breaking strength of the interface between concrete and other materials. The machine is simple in structure, light and intuitive, easy to maintain, and can be used in the field. The digital display of test data is accurate and reliable.
