Detailed

1. Product introduction

This product is mainly used for compression deformation test (uniaxial and triaxial) of cylindrical rock and concrete specimens with an aspect ratio of 2~2.5, and shear deformation test of cubic rock with an edge length of 150mm or equal to <>mm, cement concrete, concrete and rock cemented surface.

This product is used for the following mechanical property tests (both at room temperature and in high and low temperature environments):

1. Uniaxial compression test: test uniaxial compressive strength, elastic modulus, deformation modulus (secant modulus), Poisson's ratio, softening coefficient;

2. Uniaxial creep test: test the time benefit, rheology, long-term strength of rock deformation, and obtain the viscosity coefficient;

3. Triaxial compression test: test triaxial compressive strength (under different confining pressures), elastic modulus, shear strength, Poisson's ratio;

4. Direct shear test: test shear strength, shear strength, cohesion, internal friction angle and shear strength;

5. Porosity hydrostatic test: test permeability;

6. Multipath loading test: to determine the influence of loading path on the mechanical properties of rock;

Additional tests can be carried out with the appropriate attachments:

1. Splitting test (Brazilian method): determination of tensile strength;

2. Variable angle shear test: to determine the shear strength at a certain angle;

3. Three-point bending test: determine the fracture toughness;

4. Acoustic emission system: the sonic intensity level of rock fission;
