Learn More### Meaning of Absolute Volume| Concrete Construction Magazine

Jan 01, 1976 · In designing mixes the absolute volumes of the amounts of all ingredients are calculated from the weight and specific gravities and then these are added to get the volume of the concrete made with those amounts of ingredients. As far as mixing water goes you are right—apparent volume and absolute volume are both the same as just plain volume.
