Electric Unconfined Soil Compression Test Apparatus is used for measuring ultimate strength of axial pressure of resistance axle of saturation larger soft clay. That is the force given by the axial stress to make sample broke with unconfined compressive.At the same time,Unconfined compressive strength is used to determine the sensitivity of soil. The sensitivity of soil is the ratio of Compressive strength of undisturbed soil and remolded soil.Electric unconfined compressive strength test instrument is divided into two types: electric and hand operation. Instrument is made up of base, lifting board, brace, beam, and the things that is used to measure transformation of soil, like proving ring, dial indicator, supporting frame, etc.
