Tests On Rock

Elastic modulus, core recovery, RQD, point load, density, specific gravity, bearing pressure, and UCS.

  • Modulus of elasticity

    Determination of elastic modulus supports deformation analysis and structural interaction with rock masses for design.

  • Core recovery & RQD calculation

    Core recovery and rock quality designation (RQD) quantify drill core integrity and rock mass quality for engineering classification.

  • Point load test

    The point load test provides an index strength for rock and can be correlated with uniaxial compressive strength for classification.

  • Density

    Rock density (bulk and dry) supports weight–volume relationships and design calculations.

  • Specific gravity

    Specific gravity of rock solids supports porosity and unit weight estimates.

  • Allowable bearing pressure

    Allowable bearing pressure on rock is derived from strength, weathering, and discontinuity data for foundation design.

  • Unconfined compression test

    The unconfined compression test measures the compressive strength of rock specimens under axial load without lateral confinement.
