Use a nominal planning mix only where the specification permits it. For design concrete, enter the approved quantities per cubic metre and scale them to the pour.
Follow the method, check the example and review the assumptions.
Nominal mode splits adjusted dry volume by ratio parts. Design mode multiplies finished volume by each user-supplied quantity per m³.
For 1 m³ at a 1.54 dry factor and 1:2:4 ratio, the loose shares are 0.22 m³ cement, 0.44 m³ sand and 0.88 m³ aggregate.
This illustrates the method; your inputs determine your result.No. The calculator explicitly avoids that assumption. Use the approved project mix or supplied per-m³ quantities.
No. It only scales values you enter from an approved design or specification.
