Question
Calculate the weight of moist gravel that should be in a batch if the design mix requires concrete to have
water-cement ratio of 0.45, dry gravel of 1258 kg/m3, water of 122 kg/m3 and 6% of air content. Use the
following:
Gravel
Specific Gravity = 2.65
Moisture Content = 2.5%
Absorption = 4%
Sand
Specific Gravity = 2.42
Moistur Content = 2.17%
Absoprtion = 1.86 %
