The proportioning of concrete mixtures is a fundamental aspect of civil engineering, requiring iterative calculations to balance workability, strength, durability, and economy. While the American Concrete Institute (ACI) Committee 211 provides the standard "Normal, Heavyweight, and Mass Concrete" mix design methodology, manual application is prone to arithmetic error and time-consuming iteration. This paper explores the development of a robust Excel-based computational tool that automates the ACI 211.1-91 procedure. We examine the algorithmic translation of empirical tables, the handling of aggregate moisture correction, and the logic structure required for a dynamic mix design sheet. aci concrete mix design excel sheet
