In this labaratory physical and mechanical properties of rock samples, taken from the surrounding rocks of underground structures (galleries, tunnels, underground openings) and natural building stones like marble, travertine, are determined.
To carry out all these tests;
- a stiff testing machine with 3.12 MN loading capacity and 52.5 MN/mm stiffness under static and dynamic conditions
- a testing machine with 300 ton capacity for uniaxial and triaxial compressive strength tests
- bending strength, direct and indirect shear strength tests apparatus
- seismic velocity measurement (pundit) device
- rock quality index measurement devices
High standart sample preparation facilities also exist to take samples from all types of rocks.
Tests to determine physical and mechanical properties are the followings;
Physical Property Tests
- Density
- Porosity
- Water Absorption
- Permeability
- Seismic Velocity (PUNDIT) (P., S. Wavelength )
- Slake Durability Index
- Swelling Index
Mechanical Property Tests
- Uniaxial Compressive Strength (including Modulus of Elasticity and Poisson’s Ratio Determination )
- Indirect Tensile Strength
- Direct and Indirect Shear Strength
- Triaxial Compressive Strength
- Point Load Strength
- Bending Strength
- Impact Strength
- Schmidt Hammer Hardness Index
- Mohs Hardness Index
- Abrasiveness Index
- Shore Hardness Index
