The "heart" of the calculation determines the Fine Aggregate (Sand) weight. This is the only ingredient not looked up directly; it is solved for by subtraction. aci concrete mix design excel sheet

The Equation: $$V_Total = V_Water + V_Cement + V_Air + V_Coarse + V_Fine$$ | Parameter | Symbol | Example Value |

In Excel, this is calculated in a column where specific volumes are derived: The "heart" of the calculation determines the Fine

The sheet should separate Inputs (User Interface) from Calculations (Backend).
