Bibliography

This European Standard specifies a method for taking cores from hardened concrete, their examination, preparation for testing and determination of compressive strength.NOTE 1This European Standard does not give guidance on the decision to drill cores or on the locations for drilling.NOTE 2This European Standard does not provide procedures for interpreting the core strength results.NOTE 3For the assessment of in-situ compressive strength in structures and precast concrete components EN 13791 may be used.
