Concrete Theoretical Air Calculator – Excel Spreadsheet Tool
Concrete Theoretical Air Calculator – Excel Spreadsheet Tool
Quickly calculate theoretical air, gravimetric air, corrected pressure-meter air, and measured-vs-design air comparison with this professional Excel-based Concrete Theoretical Air Calculator.
Built for ready-mix producers, QC technicians, batch plant personnel, concrete inspectors, lab technicians, and field testers, this workbook helps evaluate concrete air content using batch design weights, specific gravity, absolute volume, unit weight, pressure meter readings, and correction factor inputs.
Simply enter the yellow input fields, including material design weights, specific gravities, design air, unit-weight pot data, K-factor, and pressure meter reading. The workbook automatically calculates theoretical solid volume, theoretical air volume, theoretical air percentage, theoretical unit weight, actual unit weight, corrected air percentage, gravimetric air percentage, and measured air variation from design.
