Aggregate Density

The Aggregate Density is used in the calculation of the total aggregate content and of the concrete density. Since the DOE Method, used by Firstmix, uses absolute volumes, it is essential that the absolute density be used in the mix design.

  • See Relative Aggregate Density for how the Aggregate Density is obtained in Firstmix.
  • The DOE Method , used by Firstmix, assumes that aggregate densities are specified for aggregates in a saturated and surface-dry condition. However if the aggregate properties are specified in the Measurements Dialog, Firstmix also allows densities to be specified for dry aggregates.
