Water Volume Dispensed into the Mixer: Aggregate moisture variations require adjustments in the volume of water added to the mix design. For example: an aggregate density of 2400kg/m3 would require a water change of about 24 liters due to a one-percent change in aggregate moisture content. Concrete Strength: Here we are back at Abrams Law.
