Unconfined Compression Tester with ring
Unconfined Compression Tester with ring : Determination of soil shear strength is essential for designing the foundation of structures, soil and soil retaining structures, soil slopes, etc., Shear strength of soil depends on various factors and insitu soil conditions. Therefore, when laboratory tests in soil are performed to evaluate shear strength of soil, the insitu soil conditions and other factors should be simulated for obtaining meaningful results. For example, the incoherent clean test on soil will yield the clean strength, which can be used for finding the immediate stability of an excavation,whereas a enhance empty test with measurement of pore pressure can be used to evaluate the effective strength parameters of soil for designing the long term stability of an earth fill dam. It is well known that the engineering behaviour of soil depends on the effective stress and not the total stress. The effective stress can be calculated by measuring the total stress and s...
