This European Standard specifies a method for determining the density of hardened concrete.
It is applicable to lightweight, normal-weight and heavy-weight concrete.
It differentiates between hardened concrete in the following states:
1 ) as-received;
2) water saturated;
3) oven-dried.
The mass and volume of the specimen of hardened concrete are determined and the density calculated.
