ZJ Series Two Speed Strain Controlled Direct Shear Apparatus Max Vertical Load 400KPA
ZJ Series Strain Controlled Direct Shear Apparatus Of Two Speed
Application:
ZJ Two speed Strain Controlled Direct Shear Apparatus is one apparatus used to test resisting shear strength of soil specimen with two speed method, to get horizontal force, so as to obtain shearing stress while the sample is damaged. It usually adopts four specimens under the different vertical pressure (400kPa, 300kPa, 200kPa, 100kPa, 50kPa selectable). According to GB/T 50123-2019 Standard for geotechnical testing method, it is used to confirm the soil resisting shear strength coefficient, angle of internal friction and coagulable force.
