    Thank you, sir. So very helpful. NB: m to cm multiply by 100 not 1000. (Total core length/100) cm cancel cm and we take it to %

    Do you consider difference between mechanical breaks and natural induced openings on the core when measuring pieces more than 10cm ?

      Mechanical breaks or drilling breaks meet the soundness criteria when calculating RQD

    If you have pieces less that 10cm due to mechanical fracturing don't you still include them in the RQD?

      Yes, even though it's a mechanical fracture, we still consider it as a sound core piece and include it under RQD

    Why allways must be ≥ 10cm? Its just for curiosity :) tanks!!

    Sorry but you did not explain why you are calculated 3rd piece as a full for RQD.

    How do we know it's drilling induced or natural induced?

    I believe that third piece of rock can’t be included in the calculation as it is broken

    • @GeoEngineeringandScience
      @GeoEngineeringandScience  2 года назад +1

      The piece has the length of more that 10 cm; even though it is split on top, it is still included in the calculation.

      Dear Dr. , I appreciate the scientific materials you presented in the videos .
      Kindly , If possible to explain the CPT for deep compaction and two to check that required relative denisty has been achieved. If available examples for explaining.
