    - Test methods for characterizing ore comminution behavior in geometallurgy

    The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified strength should be achieved at 28

  • Aggregate Crushing Value Test

    The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report

  • What is Compression Testing?

    Compression testing is one of the most fundamental types of mechanical testing, alongside tensile and flexion tests. Compression tests are used to determine a material’s behavior under applied crushing loads, and are typically conducted by applying compressive pressure to a test specimen (usually of either a cuboid or cylindrical geometry) using platens or specialized fixtures on a universal
