    Compressive Strength of Concrete amp Concrete Cubes

    Dec 08, 2017 Compressive strength the applied pressure at which a given concrete sample fails. Characteristic strength Suppose you take a certain number of samples from a particular batch of concrete. Characteristic strength would be that compressive strength below which not more 5 of the samples are expected to fail.

  • Compressive Strength of Concrete Cylinders

    Compressive Strength of Concrete Cylinders

    The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by applying continuous load over the cylinder until failure occurs. The test is conducted on a compression-testing machine.

    The shear strength of rock joints in theory and practice

    The paper describes an empirical law of friction for rock joints which can be used both for extrapolating and predicting shear strength data. The equation is based on three index parameters the joint roughness coefficientJRC, the joint wall compressive strengthJCS, and the residual friction angle r .
