SCOPE AND FIELD OF APPLICATION
This NORDTEST method is intended for the determination of the compressive strength of cast or drilled test specimens of hardened concrete made with normally existing rock-type aggregate.
The compressive strength of hardened concrete determined according to this method refers to the medium compressive stress at rupture occurring in a cubical or cylindrical test specimen, when the stress is determined acc. to 4.4.
The method does not state the number of test specimens, nor their age, at the time of testing.
In the main, the method agrees with IS0 4012. With regard to any deviations, see Comments.
