Details : 
        Permeable stone has a high permeability, and make the water by 2 × 10-8m / s speed, but also has a low conductivity gas. The permeable stone has been carefully selected to ensure that the triaxial test a lot of pressure, no deformation. Meet BS1377; ASTM D2850, D4767 requirements. Permeable stone can be used for the triaxial test, it has a variety of specifications. Diameter 39.1,44 triaxial experiments. Diameter of 61.8 for the oedometer, direct shear apparatus, while some of the specifications can be used in the permeameter. Main specifications:
¢ 39.1 * 5mm permeable stone for the triaxial apparatus;
Φ44 * 5mm permeable stone for the triaxial apparatus;
¢ 61.8 * 10mm permeable stone used for saturation, the triaxial permeameter;
¢ 79.8 * 10mm permeable stone for stacked saturated oedometer, direct shear apparatus;
¢ 83 * 10mm permeable stone for stacked saturated oedometer;
¢ 110 * 10mm permeable stone for the triaxial apparatus;
         The permeable stone carefully selected to ensure that for the triaxial apparatus, consolidation apparatus, direct shear apparatus, penetration and other types of trials would not have happened a lot of pressure deformation.
