Calculate the field weights of the ingredients for0.047 m³ of concrete by usingACI Method of Mix Design. Job specificationsdictate the followings:
Cement content: 330 kg/m³
w/c: 0.58 (by weight, from the strength pointof view)
w/c: 0.54 (by weight, from durability point ofview)
Air Content: 1,40 %
For Fine Aggregate (Crushed): SSD Bulk Specific Gravity:2.48, Total Moisture: 5,0 % andAbsorption Aggregate: 2,8 %.
For Coarse Aggregate (Crushed): SSD Bulk Specific Gravity: 2.60,Absorption Capacity: 2.0 %, Total Moisture:1.7 % and Dry Rodded Unit Weight:1483 kg/m³.
Cement: Sulphate Resisting Cement, Specific Gravity:3.18.
