Calculate the field weights of the ingredients for 0.039 m3 of concrete by using ACI Method of Mix Design. Job specifications dictate the followings:  

Cement content: 300 kg/m3

w/c: 0.57 (by weight, from the strength point of view)

w/c: 0.53 (by weight, from durability point of view)

Fine Aggregate (SSD)/Coarse Aggregate (SSD)=0.45 (by weight)

Air Content: 1,30 %  

For Fine Aggregate (Crushed): SSD Bulk Specific Gravity: 2.47, Total Moisture: 5,0 % and Absorption Aggregate: 2,7 %.  

For Coarse Aggregate (Crushed): SSD Bulk Specific Gravity: 2.60, Absorption Capacity: 2.0 %, Total Moisture: 1.9 % and Dry Rodded Unit Weight: 1470 kg/m3.

Cement: Sulphate Resisting Cement, Specific Gravity: 3.17
