Learning Outcomes. By the end of this course, you will be able to: Identify apparatus used for determination of the unconfined compressive strength of cohesive soil in the intact, remolded, or reconstituted condition, using strain-controlled application of the axial load, including deformation indicator. Testing determines Unconfined Compressive Strength by subjecting the soil to desired water content and density. It applies compressive force to measure the average area and plots stress and strain values to derive the maximum stress, thus determining the strength. What is the main purpose of the unconfined test?equal to 50 mm, a correction is required (Fi gure 3). The unconfined co mpressive strength q u is related to the point load index with 50 mm cores Is50 as follows Beside the diametral test, the axial test and the irregular lump test have also been proposed (see Figures 2b and 2c). Strength anisotropy can also be assessed by using the point load .

AIM OF THE EXPERIMENT To determine the unconfined compressive strength of cohesive soil in the laboratory. CODE OF REFERENCE • IS 2720 (Part-10)-1973 Methods of test for soils: Part 10 – Determination of unconfined compressive strength. • IS 2720 (Part-2)-1973 Methods of test for soils: (Part 1) – Determination of water content. APPARATUS USED Unconfined. One of the parameters which affect the uniaxial compressive strength (UCS) of rock materials is the length to diameter ratio (L/D) of test cores. ASTM recommends a ratio of between 2 and 2.5, and ISRM suggests 2.5–3:1. Research has shown that high UCS values are obtained for L/D ratios <2, a very slight difference in values between 2 and 2.5, and they .
