SCOPE AND FIELD OF APPLICATION
The NORDTEST method is intended for the determination of the compressive strength of test specimens at 24 hours age after they have been made subject to heat curing.
After calibration for the compressive strength of test specimens that have been stored in the normal manner acc. to NT BUILD 203, the method may be used to evaluate the 28 days compressive strength already after 24 hours. The conditions for this are stated in the comments.
