SCOPE AND FIELD OF APPLICATION
This NORDTEST method is intended for the determination of the modulus of elasticity of test specimens made of hardened concrete with normally existing rock-type aggregate.
Two modulus of elasticity may be determined, one of which, with the identification Eo agrees with the CEB-FIPs definition of modulus of elasticity and represents the value that is obtained during the first loading.
The second modulus of elasticity, with the identification Ec' agrees with IS0 6784 and represents the value which is obtained after at least three periods of loading and off-loading. With regard to deviations from the IS0 6784, see Comments.
The method does not state the number of test specimens or the age of the specimens at the time of testing.
