Soil Mechanics – BCEE Lab Report 5 : Experiment No. 6 – Unconfined Compression Test Lab Section LJ-X Alexandre Wong Sui Cheong ID: 40176883 December 5 , 2023 3. Calculate the actual stress for the corresponding loads.Point Load test is an alternate method that can be used to adequately predict the uniaxial compressive strength of a rock material using a portable and simpler equipment. Schmidt Hammer Rebound test is also a technique used for this purpose but, it is admitted that its results are far more variable and affected by testing methods.
The uniaxial compressive strength (UCS) test is crucial in determining the strength and stiffness behavior of intact rock and is frequently utilized by industry to determine project site characteristics. A fundamental procedure of UCS testing is strain response measurement. Conventionally, discrete strain measuring devices such as extensometers and/or electric foil .

Abstract This report focuses on the analysis of uniaxial compression testing of two different materials, solid PVC and Plexi, in the Instron machine. The laboratory group not only practiced setting up and operating the Instron machine, but also was introduced to the process off using the Instron machine specifically for compression testing. Four trials were conducted.
