Once you have entered all the inputs, the sheet instantly performs: Create cells for Input Data (Specific Gravities, FM, MSA)
A robust (based on ACI 211.1) should include the following structured sections: 1. Input Parameters (Material Properties)
ws.cell(row=row, column=1, value="2. Water-to-Cementitious Ratio (from ACI Table 6.3.4)").font = subheader_font ws.cell(row=row, column=2, value="w/cm") formula_wcm = 'IF(B4>=4000, IF(B4=4000, 0.57, IF(B4=5000, 0.48, "Interpolate")), 0.68)' ws.cell(row=row, column=3, value="Formula") ws.cell(row=row, column=4, value=formula_wcm) row += 1

Complete Guide to ACI Concrete Mix Design with Excel Sheets Concrete mix design is the process of finding the right proportions of cement, water, fine aggregate, and coarse aggregate. The goal is to produce concrete that meets specified strength, durability, and workability requirements at the lowest cost.
