  • Effects of Specimen Age on the Uniaxial …

    representative and reliable UCS value, it is necessary to test the core, or wrap and seal it, at the drill site shortly after recovery. INTRODUCTION The UCS is undoubtedly the geotechnical property that is most often used in rock engineering practice. It is widely understood as an index which gives a first approximation of the range of issues that …

  • Rock mechanics testing equipment, Controls

    Rock mechanics is an important field of geotechnical engineering as it is the theoretical and applied science concerning the physical behavior of rocks and rock masses. Slopes, tunneling, dams foundations and surface constructions requires the characterization of involved rocks and the analysis of their reaction to induced stresses.


    Reference IS-9143-1979-Method for the determination of unconfined compressive strength of rock materials Objective The objective of this test is to determine unconfined compressive strength of rock.

  • Compressive strength of rocks - PetroWiki

    Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can …

  • Estimating Unconfined Compressive Strength of …

    The UCS test is commonly used as an easy and less sophisticated among all three compression test types. Other tests are also needed if further understanding of rock failure in semi-natural cases is required. In general,

  • Epslog : The Scratch Test

    The Scratch Test is the corner stone of the data acquisition and analysis integrated service proposed by Epslog. It is designed as the first step in comprehensive core analysis programs, yielding a continuous high-resolution profile of rock strength, equivalent to a series of Uniaxial Compressive Strength values.The rock strength is obtained from the analysis of several successive scratch ...

    Brinell Hardness to Identify Unconfined Compressive Strength. Rapid, non-destructive, core-based strength logs using Brinell Hardness and Ultrasonic Velocity can rapidly identify the relative rock strength in conventional cores over large depth intervals. This measurement provides a "quick-look" at geomechanical properties.
