Name: Darrell   Dahl
Heading: Volume of batch
Can you figure air content not knowing unit weight and not using a theoretical number.
Batch weights 10 yard load
17100 CA Sp GR 2.65
12180 FA SP GR 2.63
6500 Cement SP GR 3.15
2044 Water
447.2 Free Water
Preasure Air test was 5.5% and 2 1/2" slump
Unit weight unknown
Is this the correct air content?
Target weights
17190 CA
12042 FA
6500 Cement
2048 Water
3.82 % Moisture
Thank You
