This document 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.
